A high temperature three-body abrasive wear tester has been designed and made. In order to exhibit the effect of oxidation on the wear amount of specimen and to simulate various service conditions, the oxygen content in atmosphere, the time of exposing specimen in atmosphere and the intensity of abrasion can be controlled in the tester. In the temperature range 20–900 °C, both the discriminability of wear resistances of materials and the data reproducibility of the tester are quite satisfactory. Moreover, an intermittent oxidation-abrasion test procedure has been established for investigating the interaction of oxidation and abrasion at elevated temperature. By comparing the result of test performed in argon atmosphere with that in ambient atmosphere, the respective effects of oxidation and abrasion on volume loss of specimen can be clearly distinguished.
