| Abstract: |
| The influence of machined surface quality on the corrosion resistance of material surface is complex and comprehensive. The research on the effect of machined surface quality on the corrosion resistance of material surface has important guiding and practical functions on how to prolong the service life of mechanical products, predict the machined surface quality, simplify the manufacturing process and optimize the processing parameters. The mechanism of corrosion formation on machined surface was analyzed, and the factors affecting corrosion resistance were pointed out. The research progress on the effect of machined surface quality on corrosion resistance was reviewed from the aspects of mechanical and physical characteristics of machined surface and geometrical characteristics of machined surface. The research progress on residual stress, microstructure changes of machined surface and the influence of cold hardening on corrosion resistance of machined surface was mainly reported, the effects of surface texture, surface roughness and surface scars on corrosion resistance of machined surface were summarized. It is suggested that a comprehensive analysis of the interaction between multi-surface quality parameters should be carried out, and the combined effects of various surface quality parameters on the surface corrosion resistance should be studied. In order to lay a foundation for the research on the relationship between surface quality and corrosion resistance of machined surface of metal materials, the future development trend of the research on the influence of machined surface quality on corrosion resistance has been pointed out. |
