The friction coefficient and wear behavior of 316L austenitic stainless steel and 316L steel + 8vol% TiB2 + 1vol% B composites were investigated within a temperature range of 20°C to 800°C. The materials were prepared by the powder metallurgy method. The wear behavior was studied by using a ball-on-disc wear tester at room temperature. The surface before and after wear tests was analyzed using scanning electron microscopy (SEM). The results indicated that the friction coefficient and wear resistance of stel-8TiB2-1B composites depend on the wear test conditions.

W pracy określono współczynnik tarcia i odporność na zużycie dla stali austenitycznej 316L i kompozytów o osnowie stalowej zawierających 8% obj. TiB2 i 1% obj. B. Materiały do badań wytworzono z wykorzystaniem metody metalurgii proszków. Badania właściwości tribologicznych przeprowadzono, stosując metodę ball-on-disk w zakresie temperatury 20–800°C. Badania mikrostrukturalne przed testami i po testach ścierania przeprowadzono przy zastosowaniu skaningowej mikroskopii elektronowej (SEM). Wyniki wykazały, że współczynnik tarcia i odporność na zużycie zależą od warunków testów ścierania (temperatury).
