电弧增材制造AZ61镁合金的力学性能和腐蚀性能研究
Research on Mechanical and Corrosion Properties of AZ61 Magnesium Alloy for Arc Additive Manufacturing
摘要
Abstract
Magnesium and magnesium alloys are regarded as materials with considerable potential for biomedical applications,given their high specific strength,low density,degradability,elastic modulus comparable to that of the human body,and favorable biocompatibility.However,the inferior mechanical properties and corrosion resistance of magnesium alloys restrict their further applications.AZ61 magnesium alloy specimens were prepared using the tungsten inert gas(TIG)arc additive manufacturing process,and the mechanical properties of the alloy and its corrosion resistance in simulated body fluids(SBF)were investigated.The findings revealed that the ultimate tensile strength of the additively manufactured magnesium alloy specimen was 278.5 MPa,the elongation was 30.78%,and the corrosion current density of the additively manufactured magnesium alloy in SBF was 2.827×10-6 A/cm2,which was two orders of magnitude lower than that of the cast magnesium alloy.The additively fabricated magnesium alloy specimens demonstrate not only excellent mechanical properties but also good corrosion resistance in SBF.关键词
