Abstract:Surface engineering technology is the general term of surface coating technology, surface diffusion technology and surface modification technology, which can obtain specific properties without changing the overall material of the substrate. Combined with the achievements of the author’s exploration in the field of surface engineering in recent years, application and progress of surface engineering technologies were reviewed in the field of friction and wear, corrosion protection and other features. The applications of composite electrodeposition, electroless composite plating, diffusion, laser surface modification, ion implantation, friction stir processing, shot peening and sol-gel technologies in the field of material surface treatment were introduced in detail. Then, some research achievements in this field of the authors were reported. Finally, the research status and development tendency of these technologies were analyzed.
Key words: surface engineering; surface coating and plating; diffusion; surface modification; functional coating
