概要:

application/pdf<br />Journal Article<br />Assuming that the micro-asperities on semicylindrical hard asperities with spherical ends ploughing through a softer surface, analyses ware carried out on the effects of the surface topographical parameters, such as the mean heights of the micro-asperities, radius of curvature of the tips of the semicylindrical asperities etc., on the wear rate of a soft surface. The theoretical trends of … the wear rates varying with a normal load and the topography of the worn surface agreed with the experimental trends of those of Si_3N_4 pins rubbed on four kinds of ceramic disks. The wear rates of the Si_3N_4 pins and disks increased with an increase in the mean depths of grooves and r. m. s. roughness on worn ceramic surfaces. Their trends, which varied with a normal load, also agreed with those of the truncated effects on a probability density of surface heights. 続きを見る
