A friction and wear test equipment with high frequency induction heating of the sample was designed and constructed in order to investigate the tribological properties of ceramic materials up to temperatures around 1000 °C. A particular feature of this equipment was that only a small region surrounding the samples was heated. Friction and wear tests of sintered alumina were carried out. Its coefficient of friction decreased with increasing temperature up to 1200°C and this temperature dependency became more pronounced as higher contact pressures were applied. At temperatures higher than 800°C, the wear loss was far less than that at lower temperatures and a smooth, flat friction face was observed. A thin layer with very fine grains was formed at the surface, probably due to plastic flow, and this layer was thought to be responsible for both the low friction coefficient and the small wear loss. The wear loss at room temperature could be interpreted as being caused by one of either two different behavior modes which have a wear rate difference of a factor of ten. The performance of the equipment was satisfactorily demonstrated by the test of alumina ceramics.
