Mechanical Properties and Microstructure of Bionic Non-Smooth Stainless Steel Surface by Laser Multiple Processing
Source abstract
Abstract
Laser multiple processing, i.e. laser surface texturing and then Laser Shock Processing (LSP), is a new surface processing technology for the preparation of bionic non-smooth surfaces. Based on engineering bionics, samples of bionic non-smooth surfaces of stainless steel 0Cr18Ni9 were manufactured in the form of reseau structure by laser multiple processing. The mechanical properties (including microhardness, residual stress, surface roughness) and microstructure of the samples treated by laser multiple processing were compared with those of the samples without LSP. The results show that the mechanical properties of these samples by laser multiple processing were clearly improved in comparison with those of the samples without LSP. The mechanisms underlying the improved surface microhardness and surface residual stress were analyzed, and the relations between hardness, compressive residual stress and roughness were also presented.
