Abstract
Lubricant-hard-ductile composite coating compositions and methods of making the same are provided. In embodiment, a composite coating composition comprises: a lubricant phase for providing lubrication to a surface; a hard ceramic phase for providing structural integrity and wear resistance to the surface; and a ductile metal phase for providing ductility to the surface.

A composite coating composition comprising:
- a lubricant phase for providing lubrication to a surface;
- a hard ceramic phase for providing structural integrity and wear resistance to the surface;
- and
- a ductile metal phase for providing ductility to the surface.
1 more element
A method of making a lubricant-hard-ductile composite coating, comprising:
- combining lubricant particles and hard ceramic particles with an ionic metal electroplating solution;
- electroplating a substrate using the electroplating solution to form a metal coating on the substrate;
- and
- performing an electrophoresis procedure to cause the lubricant particles and the hard ceramic particles to be incorporated into the metal coating and thereby form the lubricant-hard-ductile composite coating.
1 more element
A method of applying a lubricant-hard-ductile composite coating to a substrate, comprising:
- premixing a lubricant phase, a hard ceramic phase, and a ductile metal phase to form an agglomerated thermal spray feedstock;
- and
- thermal spraying the agglomerated thermal spray feedstock on a surface of the substrate to form a coating thereon.
