ABSTRACT:
A coating is applied to the outside diameter surface of a bushing used to coldwork in a hole in a work piece. The bushing having the coating is positioned and fixed axially with respect to the hole and then expanded by an expansion mandrel with the coating on the outside diameter surface of the bushing coming into contact with the walls of the hole and the hole being coldworked. The coating reduces fretting of the coldworked joint thereby increasing the fatigue life of the joint. The bushing having the coating can be easily removed, and then replaced, by boring out the old bushing since the coating provides a margin of machining error and thereby protects the walls of the hole.
