The present investigation was performed to find out the relationship between 3-body abrasive wear characteristics and microstructure in a 0.3 wt.% C steel. The steel was heat treated under different conditions to have PF/P (Polygonal ferrite & Pearlite), B (Bainite), M (Martensite) and TM (Tempered martensite) microstructures. Three-body abrasive wear tests were carried out using a ball-cratering tester. The tester used AISI 52100 steel ball as a counterpart. The ball-surface was roughened prior to the test, which was necessary for smooth feeding of abrasive slurry into the contact between the ball and the specimen. The slurry was composed of Al₂O₃ particles (4㎛) suspended in water with a concentration of 0.75g/ml. The slurry was fed on top of the ball throughout the test at an approximate rate of 1.445g/min. All tests were performed at a normal load of 0.2 N, sliding (ball rotation) speed of 0.1m/s and sliding distance of 50m. Microstructure of the heat treated specimens was observed by an optical microscope, and the worn surfaces were observed by a stereoscopic optical microscope and SEM (scanning electron microscope). The M (martensite) specimen showed the highest 3-body abrasive wear resistance due to its much higher hardness than the others. Among the specimens with similar hardness, the PF/P (polygonal ferrite/pearlite) specimen displayed high wear resistance, where the wear proceeded by a ploughing mechanism.
