Abstract
In order to find out the prevention of wear in case of being used for the high manganese point of railway, the author carried out an experiment using an Amsler-type light load abrasion testing machine, at various slip speed, of 0-30cm/sec, and under contact pressures of 20-40kg/mm2.
The test piece of tyre is of about 0.7%C steel of standard structure, and the other material of high manganese steel is from 1050°C water-toughening.
The results are summarized as follows:
(1) Hardness of high manganese steel rises up to a certain extent at the beginning of the test. However, anti-wearing character can not be expected to increase owing to the growing of its hardness.
(2) Wear resistance effect of high manganese steel is more notable under low pressure contact (σ<40kg/mm2) than under high pressure contact (σ>40kg/mm2).
(3) Under the low pressure contact, high manganese steel is effective for sliding wear.
