• C-N films were deposited on the 20CrMo alloy steel substrate by the Plasma Source Ion Implantation (PSII) method and TiN films were coated on the same material by the Physical Vapor Deposition (PVD) method. It was found that friction coefficient of C-N coating were relatively lower than that of TiN coating, and the friction coefficients of C-N and TiN coating decreased with increasing load. Then the author puts forward the test rig, working under the conditions of 1,800 rpm, 20 N-m for 100 h. The observations by microscope showed the wear reduced. The anti-wearing performance enhanced prominently. But the TiN coated gear had a more serious friction phenomenon than C-N coated gear. This is caused by that coating of TiN, which was made at a high temperature about 500℃. And the high temperature led to the substrate intenerated and the surface hardness decreased 850 HV to 630 HV. PSII method eliminates the tempering problem of the coating of C-N films, which had higher wear resistance than TiN films. The friction and wear resistance of gears while coated by C-N films ameliorated significantly.
