The effect of zinc and calcium addition on magnesium alloy

Popis výsledku v původním jazyce

The magnesium alloys, alloyed by the low amount of calcium and zinc concurrently, are considered as a biodegradable materials for implants. However, the as-cast alloy exhibits the insufficient mechanical properties as well as corrosion resistance which are affected mainly by the presence of brittle secondary phases, such as Mg2Ca. For this reason, presented work was focused on the as-cast magnesium alloy with alloying elements (Ca and Zn) whose content did not exceed 1 wt. %, specifically MgCa0.5Zn0.5 (in wt. %). Microstructure consisted of magnesium matrix with a very low amount of Mg2Ca and Ca2Mg6Zn3 phases which crystallized along the boundaries. These phases and their localization influenced the resulted mechanical properties. The hardness was higher due to them and tensile properties were worse than the compressive ones. The addition of zinc did not improve ductility, but in the case of compressive stress-strain test, the relative deformation was satisfactory. Moreover, the corrosion resistance of as-cast alloy MgCa0.5Zn0.5 was better than pure magnesium.
