Following the Abrasion test of High Manganese Steel under the dry condition which has been reported by the author, an Amsler-type abrasion testing machine, and the condition that is at various slip speeds of 0〜15cm/s, and contact pressures of 50〜90kg/mm^2 is used. The test piece of tyre is standard structure steel, containing about 0.7% C, and the other material of High Manganese Steel is water quenched at a temperature of 1050℃. The ideal combination of High Manganese Steel and tyre was researched under the influence of lubrication in which same number of drops of #40 Motor-oil were supplied every day. The result of this research is as follows : 1) "Pitting" of the high manganese steel is less than that of the carbon steel, therefore the wearing amount of the specimen is very little and the effect of lubrication is very remarkable. 2) The fact that the effect of wear prevention on the high manganese steel is satisfactory under the influence of lubrication is supposed to be due to work-hardening.
