摘 要：A gradient nano-grained（GNG） surface layer was fabricated on an AISI 316 L stainless steel（SS） by using the surface mechanical rolling treatment（SMRT）. Reciprocating dry and oil-lubricated sliding tests of the GNG 316 L SS in air at room temperature were conducted in comparison with the coarse-grained（CG）counterpart. Worn surface morphologies and subsurface microstructures were investigated for both 316 L SS samples. 316 L SS with a GNG surface layer shows a significantly improved wear resistance, especially under oil-lubricated condition. The notably wear resistance enhancement of the GNG 316 L SS is attributed to the GNG surface layer with high strain accommodation ability and high hardness, which can reduce the wear volume in the running-in stage effectively.
