PVD (physical vapor deposition) coatings are widely used in all aspects of our life. PVD coating has many advantages over other traditional coatings, such as high hardness, high wear resistance, low friction coefficient, good corrosion resistance and chemical stability. PVD coatings are available in a variety of materials, and different coating materials have different colors, so their decorative use is particularly prominent. Many industries, such as knives, watches, and jewelry, begin to widely use PVD coatings. Today SAM Sputter Target will introduce the common materials for PVD coatings.TiN is arguably the most popular material thanks to its golden appearance, good chemical stability and high melting point. Compared with gold plating, TiN-coated films are cost-effective and durable, so they are widely used in watches and jewellery.TiCN is grayish black and has the advantages of TiC and TiN. It has high melting point, high hardness, wear resistance, oxidation resistance, corrosion resistance, etc., and has good thermal conductivity, electrical conductivity and chemical stability. Therefore, it is widely used in cutting tools, powder metallurgy and cermet products.The alumina coating formed by the TiAlN / AlTiN coating during processing can effectively improve the high temperature processing life of the processing tool. The chemical elements of the two materials are identical, except that the former has a higher titanium content and the latter has a higher aluminum content, and the AlTiN coating has a high temperature oxidation resistance of about 100 degrees higher than TiAlN. Carbide tools use this material: TiAlN is recommended when the hardness of the material is lower than HRC45; AlTiN is recommended when the hardness of the material is higher than HRC45.Cr2N coatings have good adhesion, corrosion resistance and wear resistance and are used as wear resistant coatings.
