| Abstract: |
| The applications of TiN films are extensive. TiN films on stainless steel substrate were repared using multi-arc ion plating technique. The surface hardness of the film was measured with micro hardness tester. The wear resistance of TiN films were studied using different counterparts by the ball-disk wear tester. Wear surface morphology of counterparts were investigated by OM. SEM, EDS and XPS were employed to characterize the morphology and chemical composition of wear grooves in the films. The analysis results show that the friction cofficent of TiN film is reduced with the increasement of velocity and load ot different counterparts. The friction coefficient of TiN films at counterpart of GCr15 ball is lower than that of TiN films at counterpart of Si3N4 ball in the same condition. Tribological mechanism of TiN films at counterpart of Si3N4 ball is abrasion, while TiN films at counterpart of GCr15 ball which exhibites abrasion and adherence is little wear. |
