ABSTRACT:
Interlocking metal parts that slide under pressure on one another are manufactured so that at least one metal part is manufactured by a powdered metal injection-molding method, an in order to improve the sliding behavior and to minimize the binding tendency, a non-metallic substance having a structured arrangement of molecules is admixed in powdered or granular form with the powdered metal of the metal part manufactured by powder injection molding. The substance is inert towards the metal and has a thermal stability of at least 900.degree. C. In particular, ceramic solid materials or fillers are suitable substances.
