The present investigation was performed to investigate wear-rate variation (wear-rate data scatter) in 0.2wt% C steel depending on its microstructure. The steel was heat treated to get polygonal ferrite + pearlite, acicular ferrite + pearlite, polygonal ferrite + martensite and martensite microstructure. Dry sliding wear tests were carried out using a ball-on-disk wear tester at a sliding speed of 0.1m/s. Sliding distance were varied from 300m to 710m and applied load was 100N. An AISI 52100 bearing steel ball was used as a counterpart for disk steel specimen disks. Wear rate was calculated by dividing wear volume by the sliding distance. At least five tests were conducted under the same condition, and the wear-rate data scatter in each specimen was compared. At sliding distance 300m, specimens with the polygonal ferrite + pearlite microstructure exhibited the highest deviation from the mean wear-rate. On the contrary specimens with the polygonal ferrite + martensite microstructure showed the lowest deviation from the mean wear-rate. Wear-rate deviation was related to the number of crack nucleation sites in the subsurface.
