In the last report the behavior of sliding wear of steels at ambient temperature was studied in summer and winter in Tokyo making use of various carbon steels as specimens that were melted in air or remelted in vacuum in author's Institute. But the effects of both seasons on the behavior of sliding wear could not be made clear from the above study. In this paper the behavior of sliding wear was studied at ambient temperature, 200℃, 400℃, and 600℃ making use of the same steels as in the last report to explain the above mentioned effects. The results in winter had been obtained in the last report, then the experiment in summer was performed in this study. It was found from the above mentioned results that the oxidation tendency on the new clean surface created by breaks of contact points over the friction surface may change due to the difference of the relative humidity in air between summer and winter so that the changes of the oxidation tendency may have influence on the vehavior of sliding wear. Namely a coarse oxide film can be created on the new clean surface of steel in smmer while a thick oxid film can be created on it in winter in Tokyo.
