摘要：
The aim of the present work is to determine the influence of TiB2 coating on the friction parameters in sliding pairs under lubricated friction conditions. The TiB2 coating deposited on modified surface layers of ring specimens made of 46Cr2 steel were matched under test conditions with counterparts made of CuPb30 bearing alloys. The tested sliding pairs were lubricated with 15W/40 mineral oil and 5W/40 synthetic engine oil. The lubrication of friction area with mineral oil causes the reduction of friction force and temperature in the friction area, whereas the lubrication with synthetic oil reduces the wear of the bearing and the changes in the geometrical structure of the cooperating friction pair elements. Lubrication of the friction area in the start-up phase of the friction pair by mineral oil causes faster stabilization of the friction conditions in the contact area than in case of lubrication of the friction pair by the synthetic oil.
