"I said, don't engage in these false things, if you have this time to make a fool of yourself, it's better to do your job well. I'll be even happier that way! For Shui Ruijun, who made the teacher move, Yun Fei said with a cold face.

This matter was vigorously rectified by the group company a long time ago.

But it doesn't seem to have any effect.

"Boss, this is the first time you have come to Jiuyi to inspect the work. Let's greet the boss at the door of the company, this is also one of our jobs......" Shui Ruijun didn't dare to say anything, and Guo Chuan, who was haggard, said to Yun Fei with a smile.

This made Yun Fei lose his anger in an instant.

It seems that his boss is inspecting the work for the first time after Jiuyi Materials moved to Guocheng.

"Let's all go back to work, let's go to the research room first. The research institute is now tackling key problems and needs better matching tools, but the research progress of the material factory has not been able to keep up. Lao Guo, I'm not here to scold you, what's the problem, although I mention that my boss can't provide any help technically, but in terms of logistics, there is absolutely no problem! Yun Fei went straight to the point.

Materials are the foundation.

China is not good at this in the first place, and even the aviation aluminum used in key parts of the aircraft is imported from Lao Maozi.

Even though the Jiuyi Material Factory cooperated with the 611 Research Institute of the 132 Factory to develop nickel-based superalloys, in addition to being used in aerospace rocket engines that were scrapped after only one use, they are still doing flamejet tests in the Gobi Desert in the northwest to test the working performance of this material at high temperatures.

Just such an experiment will have to be done for several years.

It is not too easy to improve material technology.

After all, China's technology is not its own, and most of it is inherited from the former Soviet Union. Can Lao Maozi be well-hearted? Will give China the most advanced technology? Just think about it.

People casually give a little bit of material technology in the thirties and forties, which was advanced technology for China, which did not have the slightest industrial foundation at that time.

I didn't look at China, and now many steel mills are using equipment and production processes that were obsolete in the sixties and seventies in small Japan. Such equipment, such a process. How can we produce good base materials?

Domestic investment in this area is not small, but these research funds are not used in key areas. Even Qin Fei and the material factories under the group company such as Beizhong have not made much breakthroughs.

The most important thing is that some of the precision testing instruments required for the study of materials cannot be produced by China's manufacturing technology.

Abroad, these top-level precision equipment and instruments are simply impossible to export to China.

Even if you get through Philip, you can't get much top-of-the-line equipment. Even the large-scale particle injection machine that I got for the Dream Computer Industry Base was second-hand equipment that others had eliminated!

No foreign company can hope for a strong competitor in China.

If Philip weren't for profit, even second-hand equipment wouldn't help Yun Fei.

"Boss. In this regard, progress is too slow, and we have nothing we can do. However, I think we should still dig up some retired old academicians from the Academy of Sciences, although they have not made much achievements in this, but after all, they have been immersed in this industry for so many years, and they will definitely be more ......experienced than us," Guo Chuan said to Yun Fei.

When Wang Bingkun was in charge of the Materials Research Institute, many projects were progressing very quickly. Although this person's character is not very good, he still has a set of methods in terms of conducting research.

And Guo Chuan can't.

Although he majored in materials, he returned to the original Rongcheng Tool Factory after graduation. Then he left the technical research position and became a manager. It wasn't until Yun Fei joined the Jiuyi Research Institute that he returned to the technology research industry again.

Wang Bingkun introduced a lot of old technicians to their research institute back then, but these old technicians were okay to do general research. However, in the research of top-level materials, there is basically not much creative power.

Dig people, especially academicians of the Chinese Academy of Sciences. This matter has to be dealt with.

"Aren't there a couple of old technicians now? Moreover, there are not many real experts in the research of tungsten and molybdenum materials in China. Our country started too late in this regard......" Yun Fei sighed.

"It's not easy to poach those academicians who haven't retired, and the Chinese Academy of Sciences has long let us do this. What's more, we can't give them any honor except money. How many people who are really engaged in technical research like Sun Lao and others care about money? "What Yun Fei said is the truth.

It's not that he doesn't want to dig the corner of the Chinese Academy of Sciences, but this corner is not easy to dig even if there is a good hoe.

"At present, the integration of physical vapor deposition and chemical meteorological deposition is the biggest problem. In addition, nano-level coating materials, regardless of titanium nitride or aluminum oxide, are difficult to really reach the nano-level, and the number of coating layers on the surface of the tool can only reach 640 layers at most, and the coating thickness has exceeded a trace of two...... "When Yun Fei changed his clothes, took off his shoes, and entered the coating process research room that cost hundreds of millions of dollars to establish through guò sterilization and electrostatic room, Guo Chuan introduced to Yun Fei.

Why do these materials need to be sterilized and dusted like the electronic real room, Yun Fei didn't pay attention to it. However, he instinctively felt that this was the right way to remove the dust, for fear that the dust carried by the researchers would contaminate the raw materials of the test and cause defects in the coating covering the surface of the tool.

The environment inside this real room should be considered the best in the whole country.

"At present, our coating film production technology is also good, and in the world, it should also be first-class, we should think more about the production process, and do more experiments. Some time ago in Huadu, I heard from a friend that Japan's Toshiba Corporation is researching the technology of thick film, composite and multi-coating. It is mainly the composite use of TiCN, TiAlN, TiAlN multi-layer, ultra-thin, ultra-multi-layer coatings and TiC, TiN, aluminum oxide and other coatings, and a lot of effort has been put into the research of the matrix. The specific plan is unknown...... "Jiuyi materials have just been successfully researched, and the cemented carbide base is covered with a single coating of titanium carbide, aluminum oxide and other coatings.

The multi-layer, ultra-thin and ultra-multi-layer coating technology is a new technology that has only begun to be proposed after entering the 21st century.

Yun Fei didn't plan to put it forward right now, but the tools researched by Jiuyi Materials had no way to fully play the performance of the five-axis machining center they studied.

He had to tell the direction of what should have been a strategic research before the basic technology was firmly established.

They have not developed ultra-thin coating technology now, but they can develop towards multi-layer, ultra-multi-layer.

The coating tool mainly relies on the coating on the surface for the finishing of the part, especially when it is used for high-speed superfinishing, it is basically cut inside the grain structure of the part, and the depth of the tool is often within a trace.

Many of the super-precision parts on airplanes need to be machined in this way.

This is why Yunfei requires their five-axis machining center to have a theoretical accuracy of less than five μ, and then the actual machining accuracy cannot exceed one or two.

The five-axis is originally a device for high-precision parts processing.

The more complex the part, the higher the machining accuracy requirements.

"Composite coatings? Boss, is there any more detailed content? As soon as Guo Chuan heard this, his eyes immediately lit up.

They have never thought about this solution, and have been thinking about how to make the coating thinner and be able to apply more layers of coating, so as to increase the wear resistance of the tool and improve the service life of the tool.

And now Yun Fei told them that foreign countries have begun to study the cross-coverage of different coating materials, how can these technicians, who have been engaged in this research for several years, not understand?

"I don't know the specifics at all, that person is a central manager of the Mitsubishi Group, and I don't know much, and when I had dinner with Wang Qingfeng, the two talked about the problem of knife consumption, and they talked about this problem. The Japanese have a stronger sense of secrecy than anyone else, after all, many of the traditional crafts in our country were stolen by them...... "These things, Yun Fei just knows."

He himself did not know exactly what process to use and what method to use.

He didn't graduate in materials, and he didn't work in this area, he was an ordinary mechanical technician.

Knowing this, it is only because he is a technician, and when he is enough to buy consumables such as knives, Wang Yi will ask his opinion, after all, these things are used on the front line. The production schedule can't keep up, and if the problem is with the tool, someone will definitely be unlucky.

And those who buy knives are often blown out of the sky, the most commonly used is what kind of process is used, and then what material is the coating, and finally how many layers they have in this coating, often those who buy knives are said to be 1,000 to 2,000, because basically no one can detect how many layers there are.

They brag in this area in order to fool the grassroots technicians who do not understand these advanced material techniques. The purpose is to get the nod of these technicians.

And the procurement is also not understood, but they will be very professional, and the purchase of these new knives can have more rebates.

Yun Fei only studied machining technology and CNC machine tools, and he had no mind or energy to engage in material technology. Now how can you tell Guo Chuan the doorway inside? (To be continued......)
