    Abstract

    Several reports show that lubrication improves the sliding properties of ceramics. This paper compares dry and lubricated wear test results. Test materials were alumina, silicon carbide and steel, all sliding on steel. Dry tests were performed with a pin-on-disk machine and the lubricated tests with a journal bearing test machine under conditions of boundary lubrication.

    In dry wear tests, material transfer from one of the surfaces to the other was found to occur while in lubricated tests this was either reduced or inhibited. Wear rates during lubricated tests were about three orders of magnitude smaller than during unlubricated tests.

    The coefficient μ of friction at the end of a test was found to lie in the range μ = 0.37–0.68 for different sliding pairs in the dry tests while in lubricated tests it remained at μ = 0.02–0.03, showing the benefits of lubrication when applicable.
