摘要
A 3-layer CH220/MCrAlX/Al composite protective coating has been designed and prepared by means of two PVD techniques, the multi-arc ion plating and magnetron sputtering so as to improve the surface stability (i.e. the oxidation and corrosion resistance properties), internal oxidation degradation of MCrAlX coating, and the interfacial stability of MCrAlX/substrate. Ti-N itself is also a composite film, consisting of δ-TiN, ε-Ti<sub>2</sub>N and α-Ti. The average composition of magnetron-sputtered MCrAlX is Co-32Cr-2.6Al-
