The present investigation was performed to investigate wear-rate variation (wear-rate data scatter) in carbon steel depending on its microstructure. Steel specimens with different microstructure were used for the investigation, which are pure iron, 0.2 wt. % C steel (0.2C), 0.45 wt. % C steel (0.45C), and bearing steel (AISI52100). The pure iron, two carbon steel and the bearing steel showed microstructure of full ferrite, ferrite + pearlite and full pearlite, respectively. Depending on carbon content, the carbon steel exhibited difference pearlite-volume fraction. Dry sliding wear tests have been carried out using a ball-on-disk wear tester at a sliding speed of 0.1 m/s. Applied load and sliding distance were varied from 50 N to 150 N and from 300 m to 710 m, respectively. 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 three tests were conducted under the same condition, and the mean deviation of the wear rate in each specimen was compared. Specimens with the ferrite + pearlite microstructure (0.2C steel) exhibited the highest deviation from the mean wear rate at 100 N. The deviation varied with the applied load, and it decreased with the increase of pearlite volume fraction. The pure iron and the bearing steel showed much less deviation. The high deviation observed from the 0.2C steel was attributed to mixed microstructure of the two phases (ferrite and pearlite).
