Effect of Ultrasonic Impact Strengthening on Surface Properties of 316L Stainless Steel Prepared by Laser Selective Melting

In order to study the effect of ultrasonic impact (UIP) on microstructure and properties 316L stainless steel prepared by selective laser melting (SLM), hardness surface layer depth direction sample were tested with a micro tester. Finally, friction wear test was assessed using The electrochemical corrosion carried out samples before after shock CHI660E workstation. results show that SLM, produces plastic deformation work hardening, which improves material enhances resistance surface. With ultrasound shocks affecting near sample, about 100 ?m is formed. After treatment, self -corrosion potential in 3.5% NACl solution slightly higher than unproofed density current also lower sample., indicating can reduce rate enhance abrasion
