ABSTRACT:
A process for manufacturing a member having a wear resistant sliding surface. The process includes the steps of providing a metallic substrate having a surface covered by a photo-resist coating, forming the photo-resist coating with a pattern of hard and soft portions, removing the photo-resist coating at the soft portions to expose surface portions of the metallic substrate beneath the soft portions of the photo-resist coating, etching the metallic substrate with the hard portion of the photo-resist coating retained thereon to form pits in the surface portions of the metallic substrate, spraying molten filler material on the surface of the metallic substrate with the hard portion of the photo-resist coating thereon, to fill the pits with the filler material of a porous structure having an oil-retaining capability, and removing the hard portion of the photo-resist coating from the metallic substrate.
