A Spinoff from Mariner

Abstract

Among the technologies incorporated into the later Mariner missions was a dry film lubricant which offered exceptional lubrication quality for reduced friction and extended wear-life of mating parts in harsh interplanetary environments. Micro Surface Corporation acquired this technology, and currently market it as WS2 modified tungsten disulfide coating. A pressurized refrigerated air application process impinges a dry metallic WS2 coating without heat, curing, binders or adhesives. The coating binds instantly to metal or resin substrates with a 20 millionths of an inch thickness. Performance has been excellent in a variety of industries, particularly in plastics where in some operations, the coating increases production by reducing drag between tool steel and resin. Other advantages include product quality improvement, extension of equipment service life and maintenance elimination or reduction.
