WEAR OF DRY FRICTION PAIRS CONSISTING OF HIGH-CARBON CHROME-VANADIUM STEELS AND HARD ALLOYS

The wear resistance of DI37-VI and EK80-VI steel is studied using a friction testing device. A sample made of high-carbon chromium-vanadium steel relative to pellets made 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 190°C . The effect of an average temperature of the samples on the wear resistance of DI37-VI and EK80-VI steel is described.
