Friction and wear behavior on 60Si2Mn steel used the heat treatment process with plant material

This paper studied the wear behavior of plant abrasive to 60Si2Mn steel on wear test machine by different heat treatment processes, the samples´ microstructures were analyzed by a metallurgical microscope, the samples´ worn surface morphology was observed by a scanning electron micro-scope(SEM). The results show that: under the experimental conditions, 60Si2Mn steel abrasive wear is dominated by the micro-cutting wear, while plastic fatigue wear is not obvious; the plant abrasive wear resistance of 60Si2Mn steel can be improveed through the reasonable combination of hardness, plasticity and toughness; under the experimental conditions, the best heat treatment process of 60Si2Mn steel against plant abrasive wear is: austenitized at 900°C, austempered at 310 °C with 30min, salt bath and temperd at 160°C with 2 hours.
