Abstract: The tribological behaviour under low amplitude oscillatory sliding of diamond coatings obtained by chemical vapour deposition (CVD), also called fretting wear, was investigated. In a ball-on-flat configuration, CVD diamond coatings deposited on flat WC-Co substrates are worn against CVD-diamond-coated silicon nitride balls as well as against uncoated corundum balls. The influence of fretting parameters such as the contact load, displacement amplitude and test duration on the wear of the CVD diamond coatings deposited on flat WC-Co substrates has been studied. A criterion was derived to distinguish between different fretting regimes. Damage mechanisms such as elastic asperity interaction, abrasive sliding, particle ploughing and adhesive interaction are related to the fretting regimes. A correlation between the wear volume generated on CVD-diamond-coated WC-Co and the dissipated friction energy has been established. Based on this correlation, a prediction of the wear damage induced on CVD diamond coatings by low amplitude oscillatory sliding is shown to be possible when the contact conditions are known.
