Abstract

The US Air Force requires solid lubricant coatings with friction coefficients at or below 9.1 from 25¦C to 815¦C. Surfaces Research has developed the first bonded coating to meet this goal. Other Surface Research coatings are close to meeting this goal.The first objective of this program is to develop the parameters for sputter deposition of the best coating. Sputter-deposited coatings will have better coating-substrate adhesion, thus better wear life.The second objective is to systematically study related solid lubricant coatings, to elucidate the mechanisms by which low friction at 25¦C is produced by certain high-temperature lubricants. Chemical composition, crystal structure and melting point/hardness will be evaluated for their relative contributions to this behavior.Insights into these mechanisms are expected to open the door to further breakthroughs in wide temperature range low friction coatings.
