Running-in Behavior in the Combination of Diamond-Like Carbon Film and AC8A Aluminum Alloy

The running-in process affects the friction and wear properties of sliding materials in machines. If it is not done correctly, serious problems such as machine seizure may occur. Diamond-like carbon (DLC) films are used in various fields as an excellent tribo-material because of their low friction c...
