Abstract: This paper intends to do some research on the influence of ion-plating TiN and Ti(Y)N coating on the life of cutting tools and the coating-substrate interfacial status. The results indicate that the life of the tool coated by Ti(Y)N is increased greatly. The data dispersion degree of the test is decreased and the reliability is increased greatly. It is mainly because Ti(Y)N coating makes the coating-substrate interfacial status improved and the bond strength is increased greatly. A systematic discussion on the micro-mechanism is made.

Key words: deposition, membranes, matrix materials, interfaces, cutters.
