Abstract :
Influence of formation of surface nano/ultrajine structure using deep rolling on plasma nitriding and tribological properties of the AJSI 316L stainless steel was investigated. Initially. the deep rolling process was carried out on the bar-shaped specimensat 15 cycles with 0.2 mmls longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received and deep rolled kind sat 450 °C and H2-25%Vol. N2 gas mixture for 5h. Surface micro-hardness and un-lubricated pin-on-ring sliding wear tests were carried out on the as-received. deep rolled, plasma nitrided and deep rolled-plasma nitrided kinds. Results revealed that deep rolled-plasma nitrided kind is shuwn the highest wear resistance than the others, due to thefurther increased surface hardness achieved via the combined process.
