Verfahren zum Verändern der Oberflächenqualität metallischer Gegenstände und Vorrichtung dafür.

摘要

A method of modifying qualities of a metallic article at a particular surface (11) of the article comprises the step of melting the surface (11) by imparting a flux of high density energy to the surface (11) to form a molten metal layer (19) and the step of adding a heat resisting element to the molten metal layer (19) by performing overlay welding to the molten metal layer (19).
