摘要

A method of processing pieces or parts of machines comprises a step of providing a machine piece or part, this piece or part comprising at least one main substrate made of metal, a step of applying a coating layer onto the machine piece or part, the coating layer having antifriction and/or wear-proof and/or sticking-preventing properties; the method further comprises a step of carrying out cryogenic cooling of the machine piece or part, this cryogenic-cooling step being simultaneously active on the main substrate and the coating layer and being subsequent to the step of applying the coating layer.
