Improving the corrosion resistance of the surfaces of a magnesium alloy against state

摘要

A method for processing of a magnesium alloy based on surfaces layer of a magnesium alloy against state (10, 20, 30, 40, 50), around the resistance of the magnesium alloy surface (16, 26, 32, 44, 52) with respect to a corrosion by the contact with water to improve, wherein the method comprises that:a surface layer, which is to be protected, with a surface of a tool (14, 24, 34, 42, 58) by a movement of the tool (14, 24, 34, 42, 58) or of the object (10, 20, 30, 40, 50) is traversed, wherein the tool surface in a sliding frictional contact against the surface layer of the article (10, 20, 30, 40, 50) is pressed, in order to the surface layer of up to a predetermined depth, and to deform without material from the surface layer is cut to the metallurgical structure of the surface layer, the changed surface layer has a greater resistance to corrosion than an untreated region of the magnesium alloy based on state (10, 20, 30, 40, 50) comprises,characterized by the,that the tool (14, 24, 34, 42, 58) the surface (16, 26, 32, 44, 52) crosses repeated, during this progressive into a continuous engagement with the surface (16, 26, 32, 44, 52) progresses.
