Abstract: A coating is provided having a first metal or non-metal nitride layer and a second metal or non-metal nitride layer wherein the first and second nitride layers are sufficiently resistant to interdiffusion to maintain respective individual layer structure and strength at an elevated operating temperature when a coating contact surface is in sliding contact with another material and wherein one of the first layer or second layer includes a component that is oxidizable at the contact surface to form a friction-reducing lubricous oxide material at the contact surface.
