摘要: Abstract The corrosive behaviors and tribological performances were investigated for chromium doped graphite-like carbon films in variable pH solutions. Results showed that the as-deposited could present good corrosion resistances aggressive solutions might be attributed to effect of chromic oxide. Also, it exhibit a great pH-dependence when sliding against Si3N4 balls tribo-chemical reactions should play significant roles superior However, poor wettability result high friction coefficient tribopair pH=14 solution.
