Abstract : This paper deals with high temperature dry sliding wear behaviour and its mechanism of carbonitrided AISI 8620 steel. The sliding wear behaviour of the carbonitrided AISI 8620 steel was investigated using a pin on disc equipment at 100°C with varying parameters like normal load and sliding velocity. The scanning electron microscopy features of the worn samples reveal that abrasion with shallow and narrower wear track is the dominant wear mechanism of carbonitrided AISI 8620 at 50 N, while at 150 N, plastic deformation is caused by high friction sliding, delamination, spalling, pitting and deep grooving. The analysis of wear track was performed using high resolution universal tribometer.
