Abstract:
A method for making a component for an antifriction bearing, the bearing including an inner ring, an outer ring and a plurality of bearing elements disposed between the inner and outer rings to permit free relative rotation of the inner ring and the outer rings, the method comprising the steps of:(a) forming a metal substrate for the component;(b) plating at least a portion of the component substrate with a sacrificial metallic plating layer to inhibit corrosion of the component substrate, the sacrificial metallic plating layer including a porous zinc alloy; and(c) coating at least a portion of the component with a mechanical protection layer to limit exposure of the component substrate or the sacrificial metallic plating layer, wherein the mechanical protection layer includes a polymer coating applied over at least a portion of the sacrificial metallic plating layer, and wherein the mechanical protection layer includes a plurality of dissimilar coating layers applied sequentially over at least a portion of the sacrificial metallic plating layer.
