SOLID FILM LUBRICANT SUBSTRATES

Abstract

A comparison of the wear life and corrosion protective ability of RIA Compound 9A and two MIL-L-8937(ASG) solid film lubricants applied to various substrates was made. The substrates used were (1) grit blasted steel, (2) zinc phosphatized grit blasted steel, (3) zinc phosphatized cadmium plated steel and (4) sulphuric acid anodized and water sealed aluminum. The following conclusions are drawn from this investigation (1) RIA Compound 9A is superior to the two qualified MIL-L-8937(ASG) lubricants. (2) Corrosion products formed in a salt fog environment do not substantially reduce the lubricating ability of RIA Compound 9A when applied to zinc phosphatized steel, (3) For maximum corrosion protection, sulphuric acid anodized aluminum, water sealed after anodizing, is the best substrate for solid film lubricant coatings. (4) For maximum wear life, zinc phosphatized steel is the best substrate for solid film lubricant coatings. (5) RIA Compound 9A is the only coating examined whose wear life is not significantly reduced by an operating temperature of 400F.
