Abstract
The wear resistance of DI37-VI and EK80-VI steel is studied using a device for investigating friction. A sample made of high-carbon chromium-vanadium steel relative to pellets of MS221, VK3M, and VK6OM hard alloys on this device carries out reciprocating motion at a rate of 0.1 m/s. The base friction path is 50 km and the average temperatures of the samples are 100, 140, and 190oC. The effect of an average temperature of samples on the wear resistance of DI37-VI and EK80-VI steel is described.
