Abstract

With the development of biomedicine, biomedical metal materials have been widely concerned because of their good toughness and reliability. AISI 316L As the main stainless steel implant material, it is widely used in fracture fixation and joint replacement objects. However, the surface of 316L has low hardness and poor wear resistance. Electrical assisted laser shock reinforcement can first power the material, and then laser shock reinforcement, which produces electric effect, joule thermal effect can improve the material performance and improve the surface hardness. In this article, pre-impact (Laser Shock Processing After Applying Electro-pulsing, LSP-AAE) with single impact reinforcement (Laser Shock Processing, LSP) of 316L stainless steel, and studying the micro-hardness, surface morphology and friction and wear characteristics after treatment, it is found that the micro-hardness improvement effect of the electro-assisted laser shock enhancement 316L is better than the single laser impact enhancement, The LSP samples and the LSP-AAE samples increased by 25.2% and 30.2%, respectively, when compared with the original samples. Using GF-I high temperature reciprocating friction wear test machine on the original sample, LSP sample and LSP-AAE sample for friction wear experiments, analyze the difference of friction coefficient and wear rate of the three samples, it is found that under the same frictional conditions, the mean friction coefficient of the original, LSP, and LSP-AAE samples were 0.48, 0.40, and 0.36, respectively. The wear rates were 5.18×10^-6, 4.76×10^-6, 4.25×10^-6 mm³s^-1 N-1. Both the reduced friction coefficient and the wear rate, LSP-AAE treatment improves 316L stainless steel wear resistance more than a single laser impact reinforcement.
