Vapor Deposited Gold Thin Films as Lubricants in Vacuum (10−11 mm Hg)

摘要: Gold thin films of 1800 A to be used as lubricants were vapor deposited on Ni, Ni-Cr, and Ni-Re substrates. Strong bonding (adhesion) durability between the film substrate found essential when are a lubricant. Factors that investigated included selection material. is directly related type structure interfacial region. Two methods preparation prior deposition investigated: (1) mechanically polished surface (2) electron bombarded surface. was at room temperature thermally etched an elevated approximately (800 °F). Strength in sliding friction experiments with hemispherical niobium rider velocity 5 ft/min. Results obtained these indicated endurance li...
