Abstract

Magnesium, magnesium alloys, or articles made therefrom are coated with metals or alloys be treating with the coating metal in a pasty or semi-fluid condition in the presence of rubbing or abrading elements. The coating metal is preferably a zinc-cadmium alloy but coating with cadmium or an alloy of tin and lead is also referred to. Magnesium articles may be coated by placing them with a zinccadmium alloy and with some galvanized iron turnings as abrading elements in an inclined rotary drum provided with internal baffles, the drum being then heated to about 290 DEG C. and rotated for about three minutes or longer. The coated articles may then be heated to about 320 DEG C. to produce a more uniform coating. To coat a flat surface, it is preferably heated to a temperature just above the melting point of the zinc-cadmium alloy and then rubbed with an iron wire brush or an iron tool which is dipped at intervals into the molten alloy. The coating alloy preferably contains 1 part by weight of zinc to 4 parts of cadmium. The coated article may then be heated in hydrogen for about 1 hour at 450-550 DEG C., the hydrogen having been dried by passing it over calcium chloride and freed from traces of oxygen by passing it over heated magnesium turnings. Further coatings of the following alloys may then be applied in succession: -(1) zinc 17 parts by weight, cadmium 134 parts, magnesium 10 parts; (2) zinc 17 parts, cadmium 134 parts, magnesium 5 parts; (3) zinc 17 parts, cadmium 134 parts. A flat surface may be given to the coating by pressing the coated article between heated graphited steel surfaces. The coating of zinc-cadmium alloy, with or without the hydrogen heat-treatment, forms a suitable base for further coatings of other metals by electrodeposition, spraying, sherardizing, &c. The process may be used in the manufacture of parts for use in alkaline storage batteries or in aircraft. Specification 402,752 is referred to.
