Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received and <a name="OLE_LINK266"></a><a name="OLE_LINK265">deep </a>rolled kinds at 450&nbsp;&deg;C and H₂-25% Vol. N₂ gas mixture for 5_&shy;h. Surface micro-hardness and un-lubricated pin-on-ring sliding wear tests were carried out on the as-received, deep rolled, plasma nitrided and <a name="OLE_LINK271"></a><a name="OLE_LINK270">deep rolled-plasma nitrided </a>kinds. Results revealed that deep rolled-plasma nitrided kind is shown the highest wear resistance than the others, due to the further increased surface hardness achieved via the combined process.</p> austenitic stainless steel, deep rolling, plasma nitriding, tribological properties. 54 63 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-1165-2&slc_lang=en&sid=1 A.
