Pulsed Vacuum Arc Ion Plating Deposition of Diamond-like Carbon Films on Stainless Steel Zhou Shun, Yan Yan! Heart (Xi'an Institute of Technology's focus on thin-film technology and optical inspection. The sample is fixed on a turntable. The rotational speed of the turntable can be adjusted, and different loads can be applied vertically to the arm.
The structural environment temperature of the disc wearer is 25'C and the humidity is 30%. The test results are shown in Table 2 and Table 2. The friction coefficient has been significantly reduced before and after the coating. The coefficient of friction of the uncoated substrate under the 5N load is 0.38, while under the same load, the friction coefficient of the sample coated with DLC film was. 12. The data is shown in Table 2. It can be seen that the anti-friction effect of DLC film is very obvious.
The friction coefficient of diamond-like diamond film under different loads at the same time, we see that friction coefficient of DLC film from high to low, and when the friction to a certain stage, the friction coefficient tends to be stable. The reason for this characteristic lies in the presence of micropores and graphite particles on the DLC surface, so the friction coefficient is high. When the friction continues, on the one hand, the exfoliated graphite particles act as a lubricant, and on the other hand, the friction causes the film and friction. The temperature rise in the secondary contact zone causes the sp3 to sp2 transformation in the micro zone, ie, graphitization, forming a graphitized transfer film, so the friction coefficient decreases.
The data in Table 2 shows that the friction coefficient decreases as the load increases.
This is because the diamond-like carbon film is more likely to undergo graphitization under high load, thereby improving the lubricating performance in the local area.

Annual Meeting of Vacuum Metallurgy Special Committee of China Vacuum Society in 2005 and Summary of National Conference on Vacuum Metallurgy and Surface Engineering 2005 Annual Meeting of Vacuum Metallurgy Special Committee of China Vacuum Society in July 2005 On the 13th, it was held at Shenyang Grand National Hotel. The meeting was unanimously agreed and reported to the Chinese Vacuum Society for approval, resulting in the fifth member of the Vacuum Metallurgy Professional Committee. The list is as follows: Chairperson: Prof. Bard Chung (Northeastern University); Vice Chairman: Prof. Yang Ke (Metal Research Institute of Chinese Academy of Sciences), Prof. Yu Xi (Shenyang Vacuum Technology Institute), Prof. Yang Bin (Kunming University of Science and Technology), and Peng Ping Professor (Lanzhou Vacuum Equipment Co., Ltd.), Wang Dong Gaogong (Jinzhou Sanjiao Vacuum Metallurgy Technology Industrial Co., Ltd.); Members: Prof. Chu Shaojun (Beijing University of Science and Technology), Senior Engineer Gao Yugong (Shanghai Baosteel Group Corporation), Professor Dong Weiguang Senior Engineer ( Xi'an Heavy Machinery Research Institute), Li Fengxi Professor Level Senior Engineer (Wuhan Iron and Steel Group Corporation), Li Zhengxian Senior Engineer (Northwest Nonferrous Metal Research Institute), Sun Baoyu Gaogong (IFC Zhongbei Vacuum Shenyang Co., Ltd.), Guo Yingzhan Gao Gong (Shenyang Baile Vacuum Technology Co., Ltd.), Zhang Zhenhou Professor Level Senior Engineer (Chinese Academy of Sciences Shenyang Scientific Instrument Development Center Co., Ltd.), Zhang Shiwei Deputy, Grant (Northeastern University), Dr. Liu Kun (Northeastern University). The meeting decided to appoint Zhang Shiwei as Secretary-General. Liu Kun and Shang Kaidong Gao Gong (Jinzhou Sante Vacuum Metallurgy Technology Industrial Co., Ltd.) were the deputy secretary generals. Next, Prof. Ba Dechun, the chairman of the committee, made the previous work report. The deputy secretary-general Dr. Liu Kun introduced the preparation and schedule of the 25-year-long conference of vacuum metallurgy and surface engineering. The delegates conducted the conference schedule. Discussed. And propose amendments. In the end, we discussed the future work and development direction of the IPC and proposed that “in order to closely follow the international frontier and combine national conditions, we will closely integrate vacuum metallurgy and surface engineeringâ€, and decide the national vacuum. The Metallurgical and Surface Engineering Conference was held every two years. The 2005 National Conference on Vacuum Metallurgy and Surface Engineering was held on July 14-17, 2005 at Northeastern University in Shenyang. The conference was organized by the Vacuum Metallurgy Committee of the Chinese Vacuum Society. Hosted by Northeastern University. More than 14 representatives from nearly one unit at home and abroad attended the meeting. The meeting was chaired by Prof. Bard Chung, Director of the Vacuum Metallurgy Committee of the Chinese Vacuum Society and delivered an opening speech.

Food is the life of the people. "Food safety is related to human health and sustainable development.
In recent years, food safety incidents occur frequently. Edible oil is a necessary consumer goods for people's life. The quality of edible oil is directly related to our food safety.
Therefore, edible oil detection is of great significance.
Edible oil detection items are generally free fatty acids.
