Abstract:
The invention is a method of treating the surface of a steel mechanical part by the successive steps of subjecting the part to finishing to lower its surface roughness; cleaning; subjecting the cleaned part to a tribo finishing step to lower surface roughness and increase wettability; and subjecting the part to ambient temperature high speed projection of tungsten disulfide platelet particles to form a dense, self-lubricating deposit on the part.
