..., and then used as a factor of knowing the wear resistance level of the design material. The mass of the specimen was measured before and after the wear test to obtain the mass loss after 5,000 rev, at temperatures of 100, 150, 200, 250, 300, and 350 °C, respectively. The densities were obtained by the procedure...
