摘要: Abstract The lubricating properties of surface films on gold, nickel, copper and iron were examined in air a vacuum. Weak physically adsorbed found to reduce friction more effectively than oxide films. In these are formed by gas adsorption, but high vacuum the gases diffuse from specimen. Surface several angstroms thick exist all metals tested over wide range friction. It is suggested that, even when high, at interface do not significantly
