The paper investigates the resistance to adhesive wear of sliding bearings consisting of a nitrided ring made of steel EN DIN 100Cr6 and a bearing pad made of lead bronze. The tested rings were nitrated in a Tenifer salt bath at 580 C/2h and in plasma of ionized gases N2/H2 at 500 C/4h. Roughness measurement and surface hardness testing were performed on the all-test samples. On tribocouples composed of a nitrided ring and a lead bronze prism, the increase in temperature, the mean friction coefficient, and the width of the wear track on the contact surface of the prism were determined after 30 s of wear using the "prism on ring" sliding method under the conditions of dry friction and lubrication with SAE 5W engine oil during 30 s of wear under load with a normal force of 6.31 N and with ring speed 1200 rpm, 1740 rpm and 2500 rpm.
