Recently, it was learned from the Science and Technology Department of Zhejiang Province that after more than three years of hard work, the self-organized growth and high-temperature self-lubrication of the V-Si-N nanocomposite hard coating funded by the Natural Science Foundation of Zhejiang Province under the responsibility of Ningbo Materials Institute of the Chinese Academy of Sciences Behavioral research has achieved phased results and is expected to replace mainstream PVD (physical vapor deposition) coating technology in the near future. Three years ago, under the joint support of the Natural Science Foundation of Zhejiang Province, Ningbo Materials proposed a new idea of ​​the nano-structure strengthening method for lubricating coatings in view of the shortcomings of the existing hard coating improvement method, and designed V-Si- N nanocomposite coating. The V-Si-N nanocomposite coating has very good wear resistance, and its wear rate is comparable to the optimal data of nano-multilayer coatings and carbon-based coatings reported in the literature. In recent months, the research team has been working on the application of V-Si-N nanocomposite coatings and has conducted high-precision machining tests on stainless steel with a company outside the province. The test results show that the coating has obvious advantages, not only the long life of the X, but also the surface finish of the workpiece being processed (up to 8 grades) and high precision. It is understood that PVD technology appeared in the late 1970s, and the prepared film has the advantages of high hardness, low friction factor, good wear resistance and stable chemical properties. The successful application in the field of high-speed steel X has caused manufacturing in various countries around the world. The industry attaches great importance to it. Wear rate is the most critical indicator for evaluating the wear resistance and engineering potential of the coating. In order to reduce the wear rate, researchers at home and abroad often use more complex coating structures (such as nano-lamination), surface treatment (ABS technology) or complex. The idea of ​​the power supply, but the effect is not obvious.
