Development of PVD technology
Oct 05, 2021| Development of PVD technology
PVD technology emerged in the late 1970s, the film prepared with high hardness, low friction coefficient, good wear resistance, and chemical stability. The initial successful application in the field of high-speed steel tools has attracted the attention of the manufacturing industry in the world, people in the development of high performance, high-reliability coating equipment at the same time, but also in the carbide, ceramic cutting tools for more in-depth coating application research. Compared with the CVD process, the PVD process has no effect on the bending strength of tool materials when the temperature is below 600℃. The internal stress state of the film is compressive stress, which is more suitable for the coating of hard alloy precision and complex cutting tools. PVD process has no adverse impact on the environment, in line with the development direction of modern green manufacturing. At present, PVD coating technology has been widely used in the coating treatment of carbide end milling cutter, drill, step drill, oil hole drill, reamer, tap, indexable milling cutter, special-shaped cutter, welding cutter, and so on.
PVD technology not only improves the bonding strength between film and tool matrix material, but also develops the coating composition from the first generation of TiN to TiC, TiCN, ZrN, CrN, MoS2, TiAlN, TiAlCN, Tin-AlN, CNX, DLC, and TA-C composite coatings.
