Study of the Wear Mechanisms of Ti(C,N) Based Cermets under Dry Sliding and Oil Lubrication

The wear of Ti(C,N) based cermets under dry sliding and oil lubrication was studied.The results showed that Ti(C,N) based cermets had low friction coefficients and high wear resistance. The wear resistance of the cermets decreased with increase of the binder content. The major wear mechanisms of Ti(C,N) based cermets were ploughing and the stripping of hard phases under oil lubrication;those under dry sliding were surface adhesion and the stripping of hard phases.The surface adhesion trend decreased with decrease of nickel content.
