Abstract: A pump is disclosed. The pump may include at least one pumping mechanism. The at least one pumping mechanism may include a barrel formed of a substrate having a bore and a plunger formed of a substrate and slidably disposed within the bore in the barrel. The pump may further include a coating disposed on the plunger. The coating may include a main layer containing a tribological material and a sacrificial break-in layer disposed on the main layer, the break-in layer containing a tribological material.

Abstract: A method of surface treating a metallic part includes steps of coating the metallic part with a tribological thin film coating, and tumbling the metallic part after the coating step to remove surface micro-particles. The tumbling step may also remove delaminated areas of the tribological thin film coating. According to some embodiments, the metallic part may be tumbled with an alkaline solution.

Abstract: A multilayer coating for a metallic surface of a component is provided. The multilayer coating includes a first coating having a metal nitride. The first coating at least partially overlaps the metallic surface. The multilayer coating also includes a second coating having a metal. The second coating at least partially overlaps the first coating. The multilayer coating further includes a third coating having a Diamond Like Carbon (DLC) material. The third coating at least partially overlaps the second coating. The first coating, the second coating, and the third coating differ from one another with respect to at least one of hardness, elasticity, corrosion resistance, and lubricity. The multilayer coating includes at least ten overlapping layers having successive layers of the first coating, the second coating, and the third coating in repeating sequence.
