"As I said, don''t engage in such nonsense. If you have the time to flatter, you''d better do your job well. This will make me happier! " For the tax Ruijun who made a stir, Yun Fei said with a cold face.


    The group company issued documents on this matter a long time ago and made great efforts to rectify it.


    But it doesn''t seem to have any effect.


    "Boss, this is your first time to inspect the materials on September 1. Let''s meet the boss at the door of the company, which is also one of our jobs... "Tax Ruijun didn''t dare to say anything. Guo Chuan, with a haggard face, said to Yun Fei with a smile.


    This makes the cloud lose its anger in an instant.


    It seems that his boss inspected the work for the first time after the relocation of 91 materials to Guocheng.


    "Let''s go back to work. Let''s go to the research laboratory first. The research institute is now tackling key problems and needs better supporting tools, but the research progress of the material factory has been unable to keep up. Lao Guo, I''m not here to scold you. If there''s any problem, just mention that my boss can''t provide any help in technology, but there''s absolutely no problem in logistics! " The cloud is not directly on the subject.


    Materials are the foundation.


    China is not good at this. Even aviation aluminum used in key parts of aircraft is imported from Lao maozi.


    Even though the nickel base superalloy was originally developed by the Jiuyi material factory in cooperation with the 611 Research Institute of plant 132, it is still used in the Gobi desert in the northwest to test the working performance of this material at high temperature, except for the rocket engines that are scrapped only once.


    Just such experiments have to be done for many years.


    It is not too easy to improve material technology.


    After all, China''s technologies are not its own, and most of them are inherited from the former Soviet Union. Can Lao maozi be kind? Will it give China the most advanced technology? Just think about it.


    People casually gave some materials and technologies from the 1930s and 1940s, which were advanced technologies for China, which had no industrial foundation at all.


    I don''t see that many steel mills in China now use the equipment and production processes eliminated by small Japan in the 1960s and 1970s. How can such equipment and technology produce good basic materials?


    Domestic investment in this area is not small, but these research funds are not used in many key places. Even qinfei and Beizhong group''s subordinate material factories have not made much breakthrough.


    Most importantly, China''s manufacturing technology can not produce some precision testing instruments needed for the research of materials.


    In foreign countries, these top-level precision equipment and instruments cannot be exported to China at all.


    Cloud can''t get many top-level devices even through Philips. Even the large particle injection machine originally obtained for Xingmeng computer industry base is also a second-hand equipment eliminated by others!


    No foreign company can expect strong competitors in China.


    Philip wouldn''t even help Yunfei with second-hand equipment if it wasn''t for profit.


    "Boss, the progress in this area is too slow, and we can''t help it. However, I think we should dig some retired old academicians from the Academy of Sciences. Although they have not made much achievements in this field, after all, they have been immersed in this industry for so many years and will certainly be more experienced than us... "Guo Chuan said to Yun Fei.


    When Wang Bingkun presided over the materials research institute, many projects progressed very fast. Although this person''s character was not very good, he still had a set of skills in research.


    Guo Chuan can''t.


    Although he majored in materials, he returned to the original Chengdu tool factory after graduation, and then separated from his technical research post and became a manager. It was not until Yunfei started the 91 research institute that he returned to the technology research industry again.


    Their research institute introduced many old technicians through Wang Bingkun, but these old technicians were OK in general research, but they basically didn''t have much creativity in the research of top materials.


    Digging people, especially academicians of the Chinese Academy of Sciences, must be dealt with.


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


    "It''s not easy to dig up those academicians who haven''t retired. The Chinese Academy of Sciences has let us do this for a long time. What''s more, we can''t give them any honor except money. How many people who really engage in technical research like sun and them care about money? " Yun Fei is telling the truth.


    It''s not that he doesn''t want to dig the corner of the Chinese Academy of Sciences, but that even with a good hoe, it''s not easy to dig it out.


    "At present, the integration of our physical vapor deposition method and chemical meteorological deposition method is the biggest problem. In addition, nano coating materials, whether titanium nitride or aluminum oxide, are difficult to really reach the nano level. The maximum number of coating layers on the tool surface can only reach 640, and the coating thickness has exceeded a trace of two... "Wait until Yun Fei changes his clothes and takes off his shoes, Guo Chuan introduced to Yunfei when he entered the coating process research laboratory established with hundreds of millions of funds through sterilization and de electrostatic chamber.


    Why do these materials need to be sterilized and dedusted like electronic laboratories? Yunfei didn''t pay attention. However, he instinctively felt that the dust removal should be done. He was afraid that the dust carried by the researchers would pollute the raw materials tested and cause defects to the materials covered on the surface of the tool.


    The environment in this laboratory should be the best in the whole country.


    "At present, our coating film production technology is also good. It should be first-class in the world. We should think more ways and do more experiments in the production process. Some time ago, I heard from a friend in Huadu that Toshiba is studying the technology of thick film, composite and multi-component coating. It is mainly the composite use of TiCN, TiAlN, TiAlN multicomponent, ultra-thin and ultra-multilayer coatings and tic, tin, aluminum oxide and other coatings, and great efforts have been made in the research of matrix. The specific scheme is unknown... "Up to now, 91 material has just successfully studied a single coating covering titanium carbide, aluminum oxide and other coatings on the cemented carbide base.


    The multi-element, ultra-thin and multi-layer coating technology is a new technology that began to be put forward after entering the 21st century.


    Yun Fei didn''t intend to put forward it now at the beginning, but the tools studied by 91 materials simply can''t give full play to the performance of the five axis machining center they studied.


    He had to say that this should have been the direction of strategic research when the basic technology had not been firmly established.


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


    Coated tools mainly rely on the coating on the surface to finish the parts, especially when used for high-speed ultra finish machining, they basically cut inside the grain structure of the parts, and the cutting depth of the tools is often less than one thread.


    Many super precision parts on the aircraft need to be processed in this way.


    This is why Yunfei requires their five axis machining center to achieve the theoretical accuracy of five μ Then the actual machining accuracy can not exceed one second.


    Five axis is originally equipment for high-precision parts processing.


    The more complex the parts are, the higher the machining accuracy is required.


    "Composite coating? Boss, is there anything more detailed? " As soon as Guo Chuan heard this, his eyes lit up.


    They never thought about this scheme at all. They always thought about how to make the coating thinner and apply more layers of coating, so as to increase the wear resistance of the tool and improve the service life of the tool.


    Now Yunfei tells them that foreign countries have begun to study the benefits of cross coverage of different coating materials. How can they not understand these technicians who have been engaged in this research for several years?


    "I don''t know the details at all. The man is a central manager of Mitsubishi group and doesn''t know much. When they had dinner with Wang Qingfeng, they talked about the problem of tool consumption. The Japanese have a stronger sense of confidentiality than anyone else. After all, they have secretly learned a lot of traditional crafts in our country... "Yun Fei just knows these things.


    He didn''t know what process and method to use.


    He didn''t graduate from materials major, nor did he work in this field. He is an ordinary mechanical technician.


    He knows this only because he is a technician. When he can buy consumables such as knives, Wang Yi will ask him for advice. After all, these things are used by the front line. The production progress can''t keep up. If the problem occurs on the cutting tool, someone must be unlucky.


    Those who buy knives are often boastful. The most commonly used is what kind of process is used, and then what material is the coating. Finally, they say how many layers of the coating there are. Often those who buy knives say 1000 to 2000, because basically no user can detect how many layers there are.


    They boast in this regard in order to deceive those grass-roots technicians who do not understand these advanced material technologies. The purpose is to make these technicians nod.


    Purchasing also doesn''t understand, but they will install it very professionally. Only when these new tools are purchased can they have more rebates.


    Yunfei only studied machining technology and CNC machine tools at the beginning. He had no mind or energy to engage in material technology. Now how can you tell Guo Chuan the details of the doorway?
