Chapter 985

Yes, Mou Guangying has realized that Tengfei group may have mastered the technology of whisker ceramic cutting tools. Otherwise, as a pair of founders of Tengfei group, they can collude with Boeing and Airbus to become the leaders of aviation and civil aviation manufacturing industry. How can they not put the top machining tools that can process important parts of aero-engine.

But even though he realized it, Mou Guangying still felt a little unreal.

You know, it's a whisker ceramic tool. Although it's only a part of metal parts processing, the technology contained in it is the world's top.

Because this is not a simple composite ceramic technology, but another crystal synthesis technology, some of which are similar to monocrystalline silicon in the semiconductor industry, or the metal single crystal structure on the turbine blade of an aero-engine.

It is mainly filled into the ceramic lattice of alumina with long whisker like silicon carbide crystal with extremely high strength and hardness.

This is just like laying a layer of reinforced facade on the outside of a built house to make up the gaps between bricks and the defects left by concrete filling, which can make the house more solid and durable.

The effect of this kind of whisker ceramic cutting tool is the same. According to the calculation, after integration, the bonding force between the long whisker and the lattice can reach the ultra-high strength level of 4500 MPa.

In addition, it is evenly distributed on the alumina matrix structure, which plays the role of strengthening the brittle body with fiber in the glass fiber, so that the tensile strength of the whisker ceramic tool is greatly improved, and the tool is not easy to deform and fracture when machining difficult metal parts; the rotation speed is ten times higher than that of the coating hardened tool.

The description of the whole technology is already very complicated, and the actual production is even more difficult to doubt. After all, it's not the macroscopic work of reinforcing the facade on the external wall.

However, a series of ultra-high preparation methods are needed to make the crystals of two different substances closely arranged together.

It is hard to imagine the complexity of the process, the high difficulty and the advanced technology.

If not, green leaf would not be the only company in the world that can mass produce whisker ceramic cutting tools.

It's not that other countries don't want to do it, but even if they have theories and principles, they can't do it. Let's take the most basic example. The combination of silicon carbide and aluminum oxide needs high temperature heating. What's the temperature, how long is the heating time, and whether the cooling is quick cooling or normal cooling.

These key figures are not known to anyone but the Americans.

So even if the American papers about whisker ceramic cutting tools are published everywhere, as long as these core data are not leaked, no one can copy them.

Unless you bite your teeth and smash the money over and over again and try to figure out all the data.

The problem is that the Americans can't let you come to a conclusion so easily. Before you come to a conclusion, they either dump you at a low price or make a hostile purchase, and directly give you to GG. What do you do?

Technology is difficult, and some Americans are eyeing the ceiling. It's not difficult for ordinary countries to break through, but it's difficult to reach the sky.

As a result, Tengfei group has such a sophisticated technology in aviation manufacturing industry. How is it possible? What can China's take-off group do that even Europe and Russia can't do?

"Mr. Mou Guangying? The knife in your hand... "

Just when Mou Guangying looks at Zhuang Jianye's back with a knife and is not calm, he hears someone call him. When he turns around, he finds that he is a slovenly man with fat figure, disorderly hair, metal square glasses and uninhibited atmosphere.

Mou Guangying was stunned for a moment. He said where the beggar came from. But before he spoke, he introduced himself to the convenience: "I'm Peng Chuan, senior vice president of Tengfei group. I just came from the airport. Can you show me the knife in your hand?"

As soon as he heard that it was Peng Chuan, Mou Guangying was shocked. If Zhuang Jianye's reputation at home and abroad depended on a single face, Peng Chuan's reputation in the world really depended on a pen.

Because Peng Chuan's attainments in aerospace professional processing equipment are so high that many papers have been reprinted by foreign mainstream mechanical academic journals, thus establishing Peng Chuan's academic status in this field.

Mou Guangying has also heard of Peng Chuan. Not only that, he has repeatedly read several important papers published by Peng Chuan overseas. When he was job hopping at Daewoo, he also suggested that Jin Yuzhe poach Peng Chuan from Tengfei group.

As for the reason, Peng Chuan's reason made people collapse, his wife was pregnant, and there were too many children in the family. I really didn't want to make trouble!

Well, this Comrade Peng Chuan, who was originally favored by the higher authorities and was going to focus on training, and directly served as the director of a key Machinery Research Institute after the inspection period, ruined his great future because of the old idea of raising children for old age, so he had to commit himself to Tengfei group as a small senior vice president.

Mou Guangying, of course, did not know that this authority in the field of aerospace professional equipment had such a tortuous career. In front of him, Peng Chuan's eyes behind the thick glass like the bottom of a wine bottle were staring at the knife in his hand. Just now, Zhuang Jianye's unbalanced little heart was finally stable.Although Zhuang Jianye claims to know the most about aviation technology, he still focuses more on business operation. His real technology is still a little understood. If you look at Peng Chuan who is really knowledgeable, you can see the extraordinary performance of whisker ceramic cutting tools at a glance.

So Mou Guangying handed his hands to Peng Chuan and emphasized: "it's a new product just launched by green leaf company of the United States last year. Daewoo wants to set foot in the production of aero-engine, so it has introduced a number of new products."

Peng Chuan took the props into his hands, looked around and nodded: "it's really from the green leaf company of the United States, and the quality is pretty good." Then he looked up at Mou Guangying: "how many sets of such props are there?"

"12 sets!" Mou Guangying replied.

Peng Chuan nodded again, and then handed the tools in his hand to the assistant behind him: "write down that 12 sets of whisker ceramic tools are equivalent to the medium level of our whnb series ceramic tools. The mainstream aero-engine manufacturers probably won't want them. Send them to the gas turbine manufacturers. Their D-30 series small gas turbine production can still be used. How to say, it's Dayu Huagao We can't waste it. "

Mou Guangying thought that Peng Chuan would treat 12 sets of whisker ceramic cutting tools as treasures like him. If you don't treasure them, you should be excited. You should know that such high-end machining tools have export restrictions, and you can't buy them casually.

As a result, in Mou Guangying's expectant eyes, Peng Chuan's words brought down the brain of the aviation expert from an island.

Medium level?

Don't you want it from mainstream aircraft manufacturers?

Can it only be used in small gas turbines for civil use?

Can't we waste it?

Whnb series ceramic cutting tools?

……

Gan! What on earth is this?
