Corrosion resistance of AZ31 alloy after treatment with high current density impulse or/and laser irradiation in Hank’s solution

Abstract

In this article, we have introduced a new method that can improve the corrosion resistance of AZ31 alloy. We compared the biodegradation of AZ31 alloy foil treated with a high current density impulse (HCDI), laser irradiation (LI) and HCDI-LI with that of the untreated one. The rate of the biodegradation of AZ31 alloy treated with HCDI-LI was lower than those of the untreated one, the alloy treated with HCDI or LI. Thus, the improved corrosion resistance of the AZ31 alloy treated with HCDI-LI allows its use for medical purposes.
