Abstract

The purpose of this study is as follows : two groups of carbon steels were studied on effects of the melting processes, the metallographic structures, the seasons of summer and winter in Japan and the annealing in vacuum on the behavior of sliding wear at ambient temperature to 600°C, at which the oxidation tendencies of steels were taken into consideration. One group had benn produced in air by a high frequency furnace, and the other had been remelted in a high frequency vacuum furnace after the porduction in air.The relations between the results of wear test and the oxidation tendencies that were measured from increases in weight of the specimens heated at 700°C for 1 hour to oxidation were studied in the first place. Then, the effects of both seasons of summer and winter and the annealing in vaccum before the wear test on the behavior of sliding wear were studied at ambient temperature.The results showed that the macroscopic oxidation tendency and the microscopic one must be considered in the study of the sliding wear, when the oxidation tendency obtained by heating at 700°C for 1 hour is called the macroscopic one and the oxidation tendencies of the broken surface at the welding contact points on the sliding area is called the microscopic one.
