中文摘要：
Laser multiple processing, i.e. laser surface texturing and then Laser Shock Processing (LSP), is a new surface processingtechnology for the preparation of bionic non-smooth surfaces. Based on engineering bionics, samples of bionic non-smoothsurfaces of stainless steel 0Crl 8Ni9 were manufactured in the form of reseau structure by laser multiple processing. The mechanicalproperties (including microhardness, residual stress, surface roughness) and microstructure of the samples treated bylaser multiple processing were compared with those of the samples without LSP The results show that the mechanical propertiesof these samples by laser multiple processing were clearly improved in comparison with those of the samples without LSP Themechanisms underlying the improved surface microhardness and surface residual stress were analyzed, and the relations betweenhardness, comnressive residual stress and roughness were also presented.
