“…In this work, the situation was different because the sample was Ti3SiC2 based-composite with 70 vol% of Ti3SiC2. At RT, comparatively, Ti3SiC2 and composites of Ti3SiC2 with 15vol% Ag, with 15vol% PbO, and with 15vol% PbO-15vol% Ag showed wear rates of 2 × 10 −3 mm 3 /(N•m), 3 × 10 −5 mm 3 /(N•m), 2 × 10 −4 mm 3 /(N•m), and 2 × 10 −4 mm 3 /(N•m), respectively, during sliding against Inconel 718 at 5N and 0.1 m/s [20,22]. These results showed that the incorporation of 15vol% Ag or 15vol% PbO or 15vol% PbO-15vol% Ag can decrease the wear rate of Ti3SiC2 by at least an order of magnitude at RT.…”
