Abstract
A method for resisting galling of two coacting threaded members (10, 16) is provided. The method includes depositing a material film (36) by high energy level ion plating onto the machined surfaces (12, 14) of at least one of the threaded members (10, 16) for providing a thin mechanically insulating film (36) on the threaded member (10, 16) having a low shear stress value.
