Abstract
A process for forming a coated article having a wear resistant coating that minimizes the generation and effects of wear debris is provided. Three independent mechanisms are operative: hard crystalline debris are avoided by specifying that all coating phases harder than 1000 VHN be amorphous, large wear debris from the coating are avoided by including finely dispersed porosity in the coating, and debris in the wear area is removed by a textured surface on some portion of the coating. The process for applying the coating need not use materials that are extremely hazardous to man and the environment.
