Process for manufacturing a wear-resistant coating.

摘要

A process is disclosed for manufacturing a wear-resistant coating on the surface of a screw, which can be used in a plastication device, with which a coating material is applied to the basic steel body of the screw and firmly bonded to this by the action of heat and with which the coated screw is subsequently cooled. The coating material, containing at least 71% molybdenum, is introduced into a laser beam, melted in the same and using the same is applied to the basic body in such a manner that at least the outer region of the basic body is brought into a molten state.
