The constant extension rate tensile of AZ31B magnesium alloy with Si-contained coating in dynamic simulated body fluid

Abstract

The tensile fracture characteristics of AZ31B magnesium alloy with Si-contained coating was studied using a constant extension rate tensile in dynamic Hank's solution. The study showed that the fracture characteristics of the uncoated and coated AZ31B magnesium were different. The uncoated alloy exhibited predominant intergranular cracks while the coated revealed mixed intergranular and transgranular mode failure. The mechanical integrity of the coated AZ31B magnesium alloy was improved compared with the uncoated. © 2013 The Hard Tissue Biology Network Association Printed in Japan, All rights reserved.
