AN INVESTIGATION ON 3-BODY ABRASIVE WEAR TEST AT ELEVATED-TEMPERATURE

A high temperature three-body abrasive wear tester has been designed a nd made. In order to exhibit the effect of oxidation on the wear amoun t of specimen and to simulate various service conditions, the oxygen c ontent in atmosphere, the time of exposing specimen in atmosphere and the intensity of abrasion can be controlled in the tester. In the temp erature range 20-900 degrees C, both the discriminability of wear resi stances of materials and the data reproducibility of the tester are qu ite satisfactory. Moreover, an intermittent oxidation-abrasion test pr ocedure has been established for investigating the interaction of oxid ation and abrasion at elevated temperature. By comparing the result of test performed in argon atmosphere with that in ambient atmosphere, t he respective effects of oxidation and abrasion on Volume loss of spec imen can be clearly distinguished.
