Abstract : An investigation was made to: (1) determine the affect of several Rock Island Arsenal solid film lubricant formulations on the corrosion protection provided by several metal substrates and (2) determine the optimum solid film lubricant-substrate combination providi5g greatest corrosion protection. Conclusions obtained from the first series of tests are: (1) the solid film lubricant coating containing graphite decreased the corrosion protection provided by all the substrates and (2) the other solid film lubricant coating increased the corrosion protection provided by the zinc phosphatized substrate but did not substantially improve the corrosion protection provided by the other substrates. The limited exposure period to date of the second series of tests produced the following conclusions: (1) one solid film lubricant formulation greatly increased the corrosion protection provided by zinc phosphatized steel, (2) no corrosion has occurred on the remaining substrates coated with this formulation and (3) increasing the lubricant film thickness greatly increases the corrosion protection provided by the lubricant.
