Abstract

Abstract: The high hardness Cr-containing carbon films are deposited using a closed unbalanced field magnetron sputter ion plating system. The film adhesion is evaluated using Rockwell indentation and scratch methods. The thickness of films is measured using a ball rater tester. The Knoop hardness of films is determined using a micro Vickers hardness tester. Friction coefficient and specific wear rate are investigated using a Ball-on-disc tester under various applied loads against a steel ball. The effect of normal load on the tribological behavior of film is investigated. The results show that friction coefficient of films decreases with the increase in the applied loads. The transfer layer on the worm surface of counterpart ball is observed from the SEM and EDX results. The wear mechanism of Cr-containing carbon film is also discussed.

Key words: surface and interface of materials, magnetron sputtering, carbon film, wear resistance, anti-friction
