Abstract:
1. A method of making a textured coating on a wear surface of a machine component, the method comprising: providing a machine component selected from the group consisting of a fuel injector plunger, a gear, a piston, a ring, a bearing, a cam, a follower, a transmission component, and a hydraulic pump, selectively applying a mask on the wear surface of the machine component to create a pattern of exposed portions of the wear surface; depositing a tribological coating on the mask and on the pattern of exposed portions of the wear surface such that the tribological coating conforms to the shape of the wear surface with the mask, the tribological coating on the exposed portions creating a tribological pattern of intersecting lines raised above the wear surface; and removing the mask along with the tribological coating deposited on the mask to leave the tribological pattern on the wear surface and to create reservoirs between the intersecting lines of the tribological pattern, wherein the tribological pattern provides wear resistance and the reservoirs provide areas where lubricant and/or debris can accumulate.
