Tribological behavior of oil-lubricated, TiN-coated steel

The effects of titanium nitride (TiN) coatings on the tribological behavior of M50 and 52100 steels under both dry and synthetic polyol ester-based oil lubrication were evaluated using a reciprocating sliding pin-on-flat test machine. Under dry conditions, the TiN coating reduced the wear, which occurred by abrasion as well as the oxidation of the sliding surface. It also reduced the amount of wear-debris accumulation at the contact interface. During oil lubrication, wear and roughening of the contact area, usually associated with the boundary lubrication regime, was eliminated by the TiN coating. Formation of boundary film by the chemical interaction between the oil additives and wearing surface was also prevented by the TiN coating.
