摘要：

A new process for tribo-ecological coatings was developed by using electron cyclotron resonance-direct current (ECR-DC) hybrid plasma sputtering method. Ag-matrix overlays containing C and Mo for plain bearings to be used in automobile engines were successfully prepared by this method. The crystallographic state of C included into the Ag-matrix was identified as amorphous or diamond-like carbon (DLC) with high content of sp(2) bonds. Mo was partly transformed into solid lubricants such as MoOx (x = 2, 3) during sliding and decreased both the coefficient of friction and the wear rate. It also made the overlay softer to improve conformability and embeddability. The optimum Mo and C concentrations were determined to be about 1 and 2 mass%, respectively.
