Abstract

In this experiment the effects of the lamellar and globular pearlites and their combinations on the wear of carbon steel were studied in the temperature range from ambient temperature to 800°C. Therefor 0.89%C carbon steel was used as a fixed spescimen and 0.64%C carbon steel as a rotating one. The wear test machine was Dr. Okoshi's Rapid Wear Testing Machine which is the same as the one used in the last report. On the other hand the oxidation property at 200°C and the hardness at each test temperature were measured, and under consideration of these results the behaviour of wear phenomena was discussed. Further the results which one of the present authors obtained in the earlier experiment were again discussed. The results in this report show that the maximum values of wear rate at ambient temperature and 800°C were greater on the lamellar pearlite than on the globular. This is caused by the difference of the pearlitic structures, which changed not only the mechanical property but also the oxidation property of the carbon steel that is the same carbon steel.
