METHOD for producing strengthening coating on non ferrous alloys

摘要

The invention relates to the mechanical engineering and printing industries. A method for producing strengthened coating on non ferrous alloys includes application of chemical coating of Ni-Co-P from aqueous solution of nickel and cobalt salts at a temperature of 90-95 Cº for 45 min. and at pH 9-10, and after application of coating heat treatment is carried out at a temperature of for 2 hours. After strengthening the layer is formed with thickness of 13-15 microns microhardness of 8 GPa, which makes it possible to increase the durability and service life of parts.
