The friction and wear of diamond sliding on diamond

Abstract

In this paper some recent studies on the friction of diamond are reported. These include a study of friction tracks by reflection electron microscopy (REM); analysis of wear debris using electron and x-ray diffraction, and infrared spectroscopy; friction experiments with various lubricants. These researches showed that adhesion was an important factor in the friction of diamond on diamond, that water reduces the friction of diamond on diamond, and that plastic deformation could be involved in the friction at high loads.
