FRICTIONAL AND WEAR CHARACTERISTICS OF VARIOUS COATINGS USED ON SMALL CALIBER WEAPON COMPONENTS

Abstract

Friction and wear studies, in which Springfield Armory friction and wear machine was used, were continued. Information relating to the frictional and wear properties of coatings was obtained under simulated weapon conditions. Various coatings such as phosphate, chromium plate, and hard-anodized aluminum were evaluated. The rough porous coatings such as phosphated steel and hard anodized aluminum generally had high coefficients of friction when unlubricated, but exhibited good wear resistance when lubricated. Chromium plate, when unlubricated, had a lower coefficient of friction than steel of equal surface roughness. Metallic surfaces such as chromium plate and hardened steel had limited antigalling properties. Procedure is given, and results are discussed.
