This work presents the initial results of the dry‐sliding wear behavior of 3 mol% yttria‐stabilized zirconia reinforced with 5 vol% alumina‐niobium carbide (3Y‐TZP/5 vol% Al2O3‐NbC) nanocomposites sintered by conventional sintering and spark plasma sintering methods in the temperature range of 1350‐1450°C. The reinforcement of 3Y‐TZP matrix with hard nanoparticles aimed to improve wear strength of the composites. Wear tests were performed by the ball‐on‐disc method using alumina (Al2O3) and tungsten carbide with 6 wt% cobalt cermet (WC‐6%Co) balls as counter‐materials, a load of 15 N, a sliding distance of 2000 m, and a sliding speed of 0.1 m/s. Wear behavior was evaluated in terms of wear rate and FE‐SEM micrograph analysis of the wear tracks. The nanocomposite sintered at 1450°C by conventional sintering exhibited the least wear when tested with the WC‐6%Co ball. Generally, the wear mechanism showed evidence of severe wear regime with both counter‐materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
