Abstract
In this investigation we made experiments to obtain the effect of surface rolling on the abrasion resistance of steels by the Amsler abrasion testing machine under the conditions of dry and lubricated states.
A surface rolling apparatus was specially designed for this investigation. The materials applied to tests was 0.34% carbon steel. Surface rolling pressure was 258, 326, 411 and 517kg/mm2 by Hertz's formula, and experiments were also made on steels without surface rolling for comparisons.
In the abrasion tests the materials paired with the specimens were gray cast iron and were fixed, while the specimens were rotated at the peripheral velocity of 0.5m/s. Experiments were made till the rubbing distance of about 5.74km under dry state and 57.4km under oil lubrication. Amount of wear, moment of friction and temperature were measured. As the results, it was cleared that the abrasion resistance of the steels surface rolled is generally superior to that of the steels not surface rolled.
