摘要:
Disclosed is a method of manufacturing a surface treated metal member excellent in wear resistance, comprising the steps of: applying Ni--P electroplating on the surface of a metal base member and heat-treating the metal base member; and blasting, on the surface of the metal base member, fine particles having nearly spherical shapes and having an average particle size of 10-400 .mu.m.
摘要:
A machine part comprises: a base part formed of a titanium alloy or an aluminum alloy and having a roughened surface of Ra 0.5 .mu.m or above and PPI.sub.50 or above; and a Ni--P electrodeposit layer formed over the surface of the base part by an electroplating process using a Ni--P plating bath containing a stress relaxing agent, and having a stress of 20 kgf/mm.sup.2 or below. The machine part has a small specific gravity, excellent seizure resistance, wear resistance and fatigue strength.
