The material has a metallic supporting layer (4) made up of steel, and plastic sliding layer made up of polymer material. Recesses (8) is flanked by an enamel bell mouth (12) whose height is above a unstructured surface level of 10-100 micro meter and breadth is about 10-80 micro meter. The recesses and enamel bell mouth apply an undercut (16) to a normal surface (14) for directly and indirectly producing the recesses on the metallic supporting layer in a liquid, molten and solid state. The recesses are formed in a supporting layer impressed by the polymer material. The polymeric material is selected from a mixture consists of polyphenylene sulfide, protactinium, polyetheretherketone, or polyphosphoric acid, mica and iron oxide, and polyethersulfone. |
