Wear and Friction in Liquid Nitrogen with Austenitic Stainless Steel Having Various Surface Coatings
Cryogenic fuels, oxidants, and inert working fluids are important to propulsion systems for missiles. Turbopumps for handling these fluids may have bearings, seals, and other parts lubricated by the cryogenic liquids. The physical and chemical properties of most cryogenic liquids of interest are such that they might be expected to have very poor lubricating ability. It is therefore advantageous to utilize compatible slider materials in these cryogenic liquids.
