In this study, casting, extrusion, biocorrosion, and corrosive wear properties of 0.5 wt. % (Zn, Ca, and Nd) element added Mg—3 wt. % Ag alloys were investigated. According to the test results, it was observed that the grain refinement occurred with the effect of Zn and Ca element additions in the as-cast alloys and thus some mechanical properties of the alloys improved. Similarly, the extrusion process provided grain refinement and improved mechanical properties. As a result of in vitro corrosion tests, similar results were also obtained in the as-cast alloys, while this situation became more apparent in the extruded alloys and exhibited more homogeneous corrosion properties. In the corrosive wear tests, the wear rate of the extruded alloys generally showed a decreasing trend. However, both the as-cast and extruded Mg—3 wt. %Ag—0.5 wt. % Ca alloys exhibited the lowest wear rate.

可生物降解镁银合金的微观结构、机械和体外腐蚀性能

在这项研究中，铸造、挤压、生物腐蚀和腐蚀磨损性能为 0.5 wt. % (Zn、Ca 和 Nd) 元素添加 Mg-3 wt. % Ag 合金进行了研究。根据测试结果，观察到在铸态合金中添加Zn和Ca元素的影响发生了晶粒细化，从而改善了合金的一些力学性能。同样，挤压工艺提供了晶粒细化和改进的机械性能。由于体外在腐蚀试验中，铸态合金也获得了类似的结果，而这种情况在挤压合金中变得更加明显，并表现出更均匀的腐蚀性能。在腐蚀磨损试验中，挤压合金的磨损率普遍呈下降趋势。然而，铸态和挤压 Mg-3 wt. %Ag—0.5 重量 % Ca 合金的磨损率最低。
