Abstract
A pin-on-disk type friction machine was used to investigate the wear of copper under boundary lubrication conditions.
The wear of copper was found to be expressed in a wear rate equation as follows:
Under an apparent contact pressure lower than the critical pressure of hydrodynamic lubrication, no observable wear was found.
It was also found that the above wear rate equation was applicable to wear in which chemical reactions of the frictional surfaces were involved. However, the wear curves did not follow the equation when the oil used was chemically corrosive. The wear rate in those cases was determined by the frictional surface area or the concentration of reacting materials on the surfaces.
