本规范涵盖了物理气相沉积（PVD）金属零件上氮化钛涂层的应用和性能要求。该涂层通常用于增强零件的耐磨性，但用途不限于此类应用。该工艺仅限于在未因工艺温度升高而损坏的零件上进行视线应用。

This specification covers the requirements for the application and properties of a titanium nitride coating on metal parts applied by physical vapor deposition (PVD).This coating has been used typically for enhancing the wear resistance of parts, but usage is not limited to such applications. The process is limited to line-of-sight applications on parts that are not damaged by elevated process temperatures.
