TRIBOLOGICAL BEHAVIOR OF OIL-LUBRICATED TIN-COATED STEEL

[摘要] The effects of titanium nitride (TiN) coatings on the tribological behavior of M50 and 52100 steels under both dry and oil-lubricated conditions were evaluated with a reciprocating sliding-pin-on-flat test machine. Under dry conditions, the TiN coating reduced wear, which occurred by abrasion and by 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. The formation of a boundary film by chemical interaction between the oil additives and the wearing surface was also prevented by the TiN coating.
