Physical vapor deposition (PVD) technology is a method that uses physical processes to convert a material source into an atom, molecule, or plasma under vacuum conditions and finally deposits it on the surface of the substrate. The coating produced by this technology is smooth and compact, and it is well-integrated with the substrate. The working temperature used is low and the substrate material has a wide range of applications. The resulting environmental emissions are pollution-free and therefore belong to the green environmental protection processing technology. In particular, the anti-friction and wear-resistant coating plated by this technology not only has the characteristics of low friction and low wear, but also has the advantages of high hardness, strong bonding, corrosion resistance, etc. It has been widely used in aerospace and marine engineering. Machinery manufacturing and auto parts industries.
However, the plating thickness of most PVD wear-resistant coatings is less than 10 micrometers, and the thickness of PVD wear-resistant coatings designed with a special gradient interface is difficult to exceed 50 micrometers, which greatly limits its heavy load, long life, The application of high reliability component surfaces. Dr. Wang Yongxin and others from Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, through the design and control of plasma energy and state in vacuum reaction chamber, effectively reduced the internal stress accumulation caused by the bombardment effect of PVD wear-resistant coating film formation process. With the surface reverse sputtering loss, the single-layer plating thickness of a typical PVD abrasion resistant coating such as CrN is successfully achieved to 100 μm, which indicates that the use of a gradient layer, alternating layer or multiple composite structure design method is expected to achieve PVD wear resistant coating The greater thickness of the PVD coating enables the plating thickness of the PVD wear-resistant coating to enter the era of 100 μm/mm sub-millimeter. This greatly improves the load-bearing capacity and service life of the PVD wear-resistant coating. It is also complex for valves, blades, etc. The surface protection of high-reliability components under operating conditions opens up new avenues.
