Review on the Applications of Double Glow Plasma Surface Alloying for Improving Corrosion Resistance and Wear Resistance of Iron and Steel

Double glow plasma surface alloying (DGPSA) is an effective surface modification method to improve the surface properties of iron and steel materials. The technological principle and processing research of DGPSA are introduced. The research status of the applications of DGPSA for improving corrosion resistance and wear resistance of iron and steel is reviewed.
