Abstract

In this study, CrTiAlN and CrAlN coatings were deposited on the surfaces of M2 high speed steel (HSS) substrates. High temperature ball-on-disc tribometer was used to test the tribological properties of the coatings. The results showed that the surface micro-morphology of CrTiAlN and CrAlN presented closely packed structure with relatively uniform grains of circular shape and the cross-sectional morphology demonstrated columnar structures. XRD studies revealed that the coatings mainly consist of CrN, Cr and Cr2N crystal phases. High temperature wear tests illustrated from room temperature to 600 C, friction coefficients of CrTiAlN and CrAlN coatings increased at first and then decreased with the temperature elevated and the wear rate of the two coatings increased as the temperature rose. Besides, the wear rate of CrAlN coating was greater than CrTiAlN coating at the same temperature.
