Hand rubbing nuclear fusion live in the wilderness

Chapter 472 Changes in the Material World
"Three aluminum titanium holmium-diyttrium-ammonia carboxyl complex materials", plus a series of terms such as chelate, dissociation, and ion coordination, stun not only ordinary viewers in the live broadcast room.

Even most of the experts were a little dizzy from being smashed.

If these professional terms do not happen to be chemistry and alloy majors, even experts who are full of knowledge will be confused and don't know what they are.

And even if you major in chemistry and alloys, if you don't happen to be studying this area, you may be half-knowledgeable.

Because most of these nouns have only appeared in recent years.

For example, the two terms chelate and ion coordination were recently applied in the heavy metal ion sewage treatment technology in Windmill Country, while aminocarboxyl complex materials are terms just invented by the frontier of biochemistry.

Neither is out of the loop enough to be known by most experts.

For the first time, the experts in the live broadcast room experienced the same emotions as ordinary audiences, began to doubt life, and began to doubt whether the knowledge in their minds was all fake.

However, when Korean Won said that this material was developed in the last more than a month of the last live broadcast, countries immediately began to browse the live broadcast recordings, and soon found the smelting video of this material and watched it carefully.

'Three aluminum titanium holmium-diyttrium-ammonia carboxyl complex material' is an alloy powder made of two metals, aluminum and titanium, doped with two rare metals, holmium and yttrium, and ammonium carboxyl group materials.

Its principle is to use the strong co-bond ability of the atoms of two rare metals, holmium and yttrium, to form a relatively stable aminocarboxyl group that is easy to fall off at high temperatures.

In a high temperature environment, this 'trialuminum titanium holmium-diyttrium-aminocarboxyl complex material' can easily remove the aminocarboxyl group. After the aminocarboxyl group is removed, the atomic bonds of the two rare metals holmium and yttrium can quickly Co-build other metal atoms to form a stable metal ion chelating ring, thereby ensuring the physical strength and chemical properties of 3D printing materials.

This kind of whimsical research and development process and the principle of utilization have amazed experts from all over the world.

Especially the experts who study powder alloys, their eyes widened in amazement, and they wished to see the overall configuration process of the "trialuminum titanium holmium-diyttrium-ammonia carboxy complex material" a thousand times, even if they were dead. to be inscribed on the stele.

In fact, the composite of metal materials and other materials is not without.

But in general, composites formed by connecting metallic materials and other materials to each other are not stable.

such as ceramic-metal composites.

However, no matter whether mechanical connection or adhesive connection is used, or brazing connection, microwave connection, ultrasonic connection and other methods, the formed metal-ceramic composite materials have considerable shortcomings.

Because of the different bond types between ceramics and metals, it is difficult to achieve a good metallurgical connection.

That is to say, the composite smelting of ceramics and metals cannot achieve the fusion of atoms to form stable grain boundaries like metal and metal smelting into alloys.

Secondly, the thermal expansion coefficients of ceramics and metals are very different, and the composite joints of the two materials are prone to generate large residual stress, which will reduce the strength of the joints.

Of course, this problem does not only occur on ceramic metal composite materials, but basically all bridges between metal and other materials have this problem.

After all, the thermal expansion coefficient of metal is much larger than that of other materials.

But this problem is fatal for metal composites.

Because the thermal expansion coefficient of the metal is high, the joint of the two materials will have inconsistent expansion coefficients when subjected to high temperature, and then fall off.

In addition to the above two most critical problems, there are various troubles such as poor wettability of the ceramic surface and difficulty in determining the connection process.

Therefore, the composite of metal and non-metal materials has always been a difficult problem in the material field, and it is also a key research direction.

This is because in modern aerospace, power electronics, energy transportation and other fields, a single material can no longer meet the increasingly abnormal needs.

Often only composite materials can cope.

Such as metal-ceramic composite materials, if a good combination can be achieved between the two.

The scope of application is quite broad.

Metal materials have the advantages of excellent shock resistance, heat resistance, good toughness, and strong ductility, while ceramic materials have the characteristics of high hardness, good heat resistance, and corrosion resistance.

If the two can be combined, the new composite material will have various properties such as high hardness, high temperature strength, good creep performance, corrosion resistance, and fatigue resistance.

Combining the two materials can not only make full use of the excellent properties of the two materials, meet the requirements of complex components, but also reduce costs.

In addition, this is also of great significance to the development of the material industry, and it can even be said to be a historic breakthrough.

Of course, it does not mean that any kind of metal can be combined with ceramics, nor does it mean that it will have excellent performance when combined.

However, this broad prospect has caused countries to pour a lot of funds into research.

Unfortunately, there has been no progress in this research direction.

However, the unexpected surprise came so quietly. This kind of "trialuminum titanium holmium-diyttrium-ammonia carboxy complex material" that was not explained in detail by the anchor in front of me gave the material industry a shot of chicken blood and made everyone All material experts became excited.

Although this material can only be used to bridge the atomic bonds between metals at present, the emergence of aminocarboxyl groups has made experts from various countries see a bright road.

The aminocarboxyl group is not a metal material, but a chemical biological material.

And since this chemical biomaterial can perfectly fit the atomic bonds of metal materials, it means that the perfect combination of metal atomic bonds and non-metallic materials is completely feasible.

It has been confirmed that at least the atomic bonds of two rare metals, holmium and yttrium, can perfectly combine with other non-metallic materials.

As for the remaining metals and other non-metallic materials, they can experiment bit by bit to find out how to bridge the atomic bonds of metal materials with those of other materials.

This is a huge change for the materials industry.

Just like humans in the primitive period can only use stones, and they will refine and use copper and iron later.

This kind of technology promotes the entire civilization, and it can make the entire civilization achieve a qualitative leap.

Because at present, many technologies are limited by the performance of materials and cannot be broken through. Once the materials break through, technology will usher in another vigorous development.

In the simulated space, Han Yuan didn't think so much.

He grabbed a handful of 'trialuminum titanium holmium-diyttrium-ammonia carboxy complex material' powder and showed it under the camera, then put the material back into the box.

Let the X-1 industrial robot continue to work, while he himself found a water source to clean up the remaining metal powder on his hands.

Although this kind of material comes from the intermediate material knowledge passed to him by the system, in fact, to a certain extent, he has to thank the former host of Taishan base.

When he first entered the Taishan base, Han Yuan was shocked by the various animation pictures in the hall of the base.

Of course, what shocked him wasn't the appearance of Japanese manga characters in a Huaguo base.

Rather, it is the material for drawing these Japanese manga characters.

Those complicated patterns are all made of metal, and the different colors between the patterns are formed by excessive metal particles.

The red metal particles are mixed with multiple different colors such as blue and green, but they look very distinct.

Every metal particle almost perfectly displayed its own unique color, and did not merge with the metal technology next to it.

This kind of alloy drill technology that uses the color of the metal particles itself as the raw material, which can clearly transition and display the color, shocked him for a long time at that time, and it felt incredible.

At that time, South Korea could not imagine how such metal materials and patterns were designed and manufactured.

Because the smelting method of this alloy has exceeded his imagination and knowledge.

But thinking about it now, these alloy patterns are actually realized by utilizing the different bridging abilities of atomic bonds between different metal materials.

Of course, it's not that he is drifting away now, but that he has gained more knowledge. Some things that seemed mysterious before can now be analyzed to the theory behind them.

In addition to the metal particles that draw various anime characters, there is also the alloy gate in the Mount Tai base that can fluctuate like ocean waves. After getting in touch with the knowledge and information of intermediate materials, he also understood the principles behind it and the refining process. method.

Looking back now, Han Yuan has probably been able to judge the technological level of the former host of Taishan base.

He is taller than he is today, but not too much.

At least in terms of materials, he can basically manufacture all kinds of materials used in the Mount Tai base.

After washing his hands, Han Yuan pulled the camera and led the audience to the other side of the 3D printing factory.

There are printing equipment for printing X-1 industrial robot parts here.

Unlike the previous printing equipment that looked like containers, this factory building is divided into several areas.

Each area is separated by high-strength tempered glass, and inside is a metal table similar to a shock-proof table.

These metal tables can move back and forth, up and down, over a wide range.

This is to facilitate the adjustment of the NC program and to print out each component stably.

The printing of X-1 industrial robot parts is different from the printing of other parts.

Most of the materials used to print the X-1 industrial robot are various alloys. Whether it is metal bones, frames, or metal wires, their basic materials are all alloys.

But 3D printing metal powder equipment has a big problem, that is, it needs to provide a certain temperature or use laser scanning to ensure that the printed metal parts can be bonded together.

Don't forget that the 'three aluminum titanium holmium-diyttrium-ammonia carboxyl complex material' needs a temperature of [-] degrees to work and enhance the physical strength of the printed parts.

Therefore, the pipeline for transporting metal powder needs to be made of high temperature resistant alloy, so as to enhance the service life of the 3D printing arm.

Another point to enhance the service life is to keep the 3D printing arm stable.

However, if the robotic arm does not move, it will not be able to print out parts of various shapes normally.

Therefore, the movement of the mechanical arm moved to the metal platform at the bottom.

There is a complete displacement control system in the metal platform, and the program in the 3D printer can perfectly control the platform by moving up, down, left, and right instead of moving the mechanical arm.

This also allows perfect printing of metal parts.

The robotic arm only needs to be kept fixed, and the continuous output of printing materials is enough.

Speaking of the robotic arm, Han Yuan looked up at something fixed to the ceiling.

On top of this metal platform that can move itself at will, there are mechanical arms hanging down one by one.

The shape of these robotic arms is like an upside-down 'Burj Khalifa'; the bottom is thin, the top is thick, and the top is connected to the printing material delivery pipeline.

Each upside-down 'Burj Khalifa' is entrenched with more than a dozen material pipelines.

These pipelines for transporting printing materials are like the roots of old trees, entrenched on the top of the Burj Khalifa, and can squeeze out printing materials like toothpaste.

The audience in the live broadcast room were very curious about this hanging 3D printing equipment and asked questions one after another.

[Anchor anchor, is this thing finished?When it's finished, can you let us see it? 】

[Why do I feel that the robotic arm conveying printing materials above seems to be fixed?Can't move? 】

[As I said just now, the metal disc at the bottom is moving, and the one above conveying materials is not moving. 】

[Hey, this is the opposite of a normal 3D printer?Ordinary is that the pipeline moves, and the chassis is stable. 】

[Anchor, it's normal, don't take an unusual path. 】

[Can this fully print out the robot? 】

[It's nothing to play a robot, I want to see the anchor play a J20. 】

[J20: My machine is so big, you can bear it for a billion times (dog head)]

[Pro: I suggest you print an aircraft carrier here. 】

[Printer: It's too difficult for me. 】

Looking at the barrage, Han Yuan smiled and said, "It is impossible for a 1D printer to print out an ultra-complicated device like the X-3 industrial robot at one time."

"It's not just that its structure is too complicated. In addition, there are some parts that cannot be printed directly by 3D printing technology."

"For example, lithium-sulfur batteries, such as control chips, such as magnetic bearing balls, etc., as far as the current printing technology is concerned, it is still impossible to print them directly."

"These things will be produced in another factory, and then assembled through the assembly factory."

"Now the production of the X-1 industrial robot will be a complete assembly line."

"The main parts printed by the 3D printing factory, the battery will be stretched by the automated battery production factory, the control chip will be produced by the CNC lithography machine, etc., and then these things will be uniformly sent to the assembly factory for assembly."

"Compared with the previous production and manufacture of X-1 industrial robot parts by CNC equipment, 3D printing factory production can greatly simplify the production and manufacturing process and shorten the manufacturing time."

"If it takes five days to manufacture all the spare parts of a robot, with 3D printing technology, only half a day is enough."
