陶瓷涂层在工业上得到广泛地应用，特别是在切屑和成型工具方面。因为该涂层具有高的耐磨性，加涂的工具有长的使用寿命。商业上用的最多的是TiN涂层，这是因为TiN不仅具有高的硬度，而且具有化学和冶金的稳定性。从工程应用观点看, 涂层与基体的结合能力，摩擦特性是决定该涂 Ceramic coatings are widely used in industry, especially in chip and molding tools. Because of the high wear resistance of the coating, coated tools have a long service life. The most commercial use of TiN coatings is due to the fact that TiN has not only high hardness but also chemical and metallurgical stability. From the engineering application point of view, the coating with the substrate binding capacity, the friction characteristics is to determine the coating
