Abstract
Methods for forming carbon-based lubricious and/or wear-protective films in situ on the surface of steel alloys are provided. The methods use chromium-containing steel alloys, molybdenum-containing steel alloys, and steel alloys that contain both copper and nickel. When such alloys are subjected to a rubbing motion in the presence of a hydrocarbon fluid, the chromium, molybdenum, copper, and nickel in the steel alloy catalyzes the formation of solid carbon-containing films that reduce the friction, wear, or both of the contacting surfaces.
