Abstract: The aim of the work was to improve corrosion properties of the high-ductility Mg-Sn-Zn-Zr alloy (TZK) by heat treatment and extrusion. The microstructure characteristics and corrosion behavior of as-cast, T4-treated, and as-extruded TZK alloys were investigated systematically. The results showed that extrusion can significantly refine the grain size (decreased from 120.54 to 8.45 μm) and caused fine second phase particles to be precipitated at the grain boundaries. More importantly, the extrusion process improved the corrosion resistance of TZK alloy. Hydrogen evolution test showed that the amount of hydrogen evolution of TZK was reduced from 12.881 to 5.237 mL/cm2. The weight loss test showed that the corrosion rate of TZK alloy reduced from 1.654 to 0.827 mm/a. The electrochemical test showed that the value of Ecorr increased from − 1.533 to − 1.461 V and the value of icorr reduced from 77.02 to 21.82 μA/cm2. Furthermore, the as-extruded TZK alloy had a highly protective oxide layer, a highly adherent, and dense corrosion product layer and improved the corrosion resistance. Therefore, the high-ductility Mg-Sn-Zn-Zr alloy after extrusion has potential as a new biomedical material. [ABSTRACT FROM AUTHOR]
