| Abstract | ||
| Background: Mg as well as its alloys are differing from other biomaterials through providing compatible physical and mechanical characteristics to the human bones. Also, their elastic modulus and densities were somewhat close to one another and thus removing elastic mismatches between the bone and implants. Furthermore, the Mg present naturally in bone structure, and it is essential metal for metabolism. Some mechanical properties (Hardness, diametral tensile) and corrosion resistance of enforced Mg by Strontium and alloyed with another biocompatible elements (Zn, Mn) were examined. Materials and methods: 135 samples were prepared for microhardness, diametral tensile, and corrosion test, divided to two groups 1st one pure Mg as a control group, 2nd group Mg alloy with different concentration of alloying elements to select the optimum ratio for alloying elements which consist of Zinc, Manganese, and Strontium). Result: Alloying of Mg with Zn, Mn and Sr, shows improvement in mechanical properties but dropping in corrosion resistance when compared with pure Mg. Conclusions: Alloying of pure Mg by ternary Zn, Mn and Sr have a valuable improvement in mechanical micro hardness and diametral tensile properties, but increases corrosion rate in comparison with pure Mg due to the effect of galvanic corrosion. | ||
