This investigation included the effect of 1 resinpigment ratio, 2 coating thickness, and 3 wearing away of the film on the corrosion protection provided by solid lubricant coatings. Two series of solid film lubricants of various resin-pigment ratios were made using good and poor pigment dispersion techniques. These series of solid film lubricants were evaluated at several levels of coating thickness. Corrosion protection was evaluated by means of 20 Salt Fog cabinet while wear life was determined by the Falex Wear Test method. A combination friction-salt fog test was used in determining the effect of wearing away of the film on corrosion resistance. It was found that a solid film lubricant can be manufactured, using good pigment dispersion techniques, which will provide 1000 hours of salt fog protection. This lubricant showed no loss in wear life. It was also found that, by using a 0.0010 in. coating made up of two layers, salt fog life can be increased by at least 6 fold without sacrificing wear life.
