ABSTRACT:
The wear-resistant properties of a material containing PTFE and lead are improved by the addition of starch or cellulose when the solid lubricant is supported by a substrate of steel or beryllium-copper. The carbohydrate may be partially pyrolized but must not undergo oxidation. The substrate surface is preferably etched with pockets which are filled by the lubricant.
