Tian Zhiyong simply exposed a few techniques, which caused a terrifying wave in Li Yifan's heart.

Among these three technologies, the simplest one is probably boronized steel, but even the simplest boronized steel is already quite amazing, because this alloy steel can be said to be one of the concentrated steels second only to titanium alloy steel among ordinary alloy steels.

It has high hardness, wear resistance and heat resistance. It is generally used by various arms companies to make gun barrels. It is even more useful in civilian fields. Construction machinery, automobiles, motorcycles, industrial sewing machines and other parts of construction machinery are all made of this special steel.

The second is this powder metallurgy technology. This metallurgy technology is almost zero in my country at present, but in developed countries such as Europe, America and Japan, such metallurgy technology has been widely used.

Many imported automotive parts in China, especially gearboxes, engines, or turbines, are made of such special metal smelting technology.

This special metal smelting technology is generally mainly used to produce various industrial gears and bearings. The gears produced are hard, wear-resistant, heat-resistant and corrosion-resistant. The molecular divisions of the metal internal structure are more uniform than those of the finished products smelted by other methods, so they have a high service life and are tensile-resistant. This is a very advanced technology.

At present, countries with relatively developed powder metallurgy technology around the world include Germany, the United States, Japan, and several small countries in Western Europe, such as Switzerland, etc.

This technology will take a year before it is valued by some domestic companies, and will develop with difficulty under the strong advocacy of the country.

But ten years later, it developed into that kind of thing. In China, ten years later, the market situation of powder metallurgy was that there were many enterprises and small scales, and they could only produce low-end products. Moreover, the product types overlapped, and enterprises lowered prices. Everyone lacked core technologies and had backward R&D capabilities. It can even be said that there were no one. They could only produce high-energy-consuming low-end products.

This is related to the trend of rushing to everything in China, and it is also related to the high-level thoughts of superior leaders. As long as you have face, it is enough. As for what you can produce, those bullshit leaders don’t care.

As for scientific research? Don’t joke. If you have that money, it’s better to ask your leaders to go abroad a few more times and change to a few more luxury cars!

Therefore, even after ten years of vigorous development, my country's powder metallurgy technology has not developed. As for the gears needed in the gearbox, automobile bearings, and many industrial machinery gears and bearing parts, we can still only import them from abroad.

Among the three technologies that Tian Zhiyong casually reported, the most important one is the boron nitride technology.

This boron nitride is an extraordinary thing and is also a key technical product of powder metallurgy technology.

After this boron nitride is ground into a powder and then plated with this film on the metal, the metal becomes extremely hard, and even its hardness is comparable to that of diamonds.

So boron nitride is a great product for making tools for machine tool processing. A major machine tool industry such as Japan, the United States, and Germany have long been talking about this kind of thing, used on the guide rails of their machine tools and the tools used for processing.

As long as the boron nitride film is plated on an ordinary tool, the value of the tool will immediately double.

Especially the special ceramics coated with boron nitride can be compared with diamond in terms of hardness. More than ten years later, such tools are called perfect machine tool processing tools.

We can't play with this thing at all. First of all, the purity of the boron nitride we produce is not as good as others. Secondly, the coating process is even more different from others.

Although we know the principle of boron nitride coating, we just can't do it, so we can only look at the tens of billions of machine tool tools and rail markets, and can only be occupied by tools and rails from Japan and Germany.

These things are indeed what Japan's International Materials Research Institute is best at, especially the boron nitride coating technology. They can even be said to be leading the world trend, and they have always been at the forefront of the world in this regard.

The most common product used in this boron nitride coating is Nissan Teana sedan.

Moreover, the steel belt used in the so-called new generation of CVT continuously variable transmission developed by Nissan in later generations is because the steel belt is coated with this kind of boron nitride film, which makes their steel belt more wear-resistant, transmits more torque, and effectively prevents slippage. This makes their xtronic technology famous all over the world.

If you take out any of these techniques, then you will be treasures!

The bag contains 550,000 yen. Judging from the current exchange rate, it is about 550,000 yuan. However, the things that can be exchanged for 550,000 yuan are definitely worth 500,000 yuan, or even 50 billion yuan. How could Li Yifan be unhappy at this time?

But he couldn't put this happy expression on the surface. He had to pretend to be calm, otherwise Tian Zhiyong would seem to be a backbone guy, and he would have caused him any trouble.

"Haha, it's true that they are all good technologies. If Mr. Tian, ​​you can get these technologies for me, then the money will be yours."

"real?"

At this time, Tian Zhiyong didn't have much vision. In his opinion, the 5,500,000 yen was no longer a small amount. With this money, he could pay off his debts and make his son and daughter live a better life.

You can even consider moving in the apartment you live in and renting a better apartment to live in.

"Of course, am I talking about lies? Mr. Tian, ​​as long as you can get what you said before, the money is yours, and if you can get other technologies, we will give you more money. Don't worry, as long as you can get it, the money is not a problem."

"That's it! Haha, what do you think of the coating technology for synthesis of single crystal diamonds, boron nitride, and n-type doped diamond films under high temperature and high pressure?"

When Tian Zhiyong thought of making more money, he stopped hiding it and told all the good things he knew.

At this time, when Li Yifan heard that Tian Zhiyong could actually get such a technique, he could not hide his surprised expression.

At this time, Tian Zhiyong was like a dormant cat in the Japanese cartoon Doraemon. He could just flip through his pocket and he could find the baby that surprised him.

For example, this n-type diamond coating technology is absolutely a treasure!

The engines of the later Nissan Teana sedan were once included in the top ten engines in the world several times, but the engine, in terms of power and torque, was nothing surprising. However, the most commendable reason for its silent effect was very simple, because Nissan engineers coated the pistons of their engines and the cylinder walls of the engines, which greatly reduced friction and noise.

Moreover, the diamond coating is the same as the boron nitride coating, which can increase the hardness of metal tools and can be used to produce machine tools.

And the production of single crystal diamond at high temperature and high pressure is even more amazing. You should know that the cutting heads of the tools used in many machine tools are the diamond produced in this kind of industrially produced, and the price is very expensive.

It is generally used to process special industrial hard parts such as aerospace, ships, submarines, etc., and this kind of tool is very expensive.

There are a few countries in the world that other countries cannot produce at all. If this technology can be achieved, the domestic market in China alone will be enough to eat enough.

This Tian Zhiyong is indeed full of treasures! Li Yifan's eyes at Tian Zhiyong at this time had changed a little. He originally wanted to obtain some special metal smelting techniques and formulas through this guy, but unexpectedly, this guy just shook his arms and so on and so on, so many good things fell out!

Thinking of this, Li Yifan's ambition also expanded. You should know that there are far more good things in Japan's National Materials Research Institute.

This National Institute of Materials Research was based on metal research at that time, but after continuous development and growth, their main skills were no longer limited to the smelting and processing of special metals.

In recent decades, they have achieved countless achievements in the processing and technology of electronic products. Japan's Toshiba, Sanyo, Panasonic, Sony and other companies have all gained a lot of benefits from the development and growth.

Especially the Japanese are most proud of, the production of electronic components, such as microcapacitors used on computers or mobile phone motherboards, and various electronic components, has always been the specialty of the Japanese, but the basic technology for producing these things almost all comes from this material research institute.

So now that Li Yifan is inflating his ambitions, he is of course focusing on these good things because these things are more valuable.
Chapter completed!
