Abstract
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.
