Abstract Scope |
There is considerable work aimed at improving the strength and corrosion resistance of Mg alloys. For the present work, the influence of alloying addition on the hardness and corrosion behavior of Mg alloys is investigated using high-energy ball milling (HEBM). Binary alloys were synthesized using HEBM and consolidated using cold compaction and spark plasma sintering. Phase analysis, hardness, and microscopic studies for alloys were done for comparison. Corrosion behavior was evaluated using potentiodynamic polarization tests in 0.1 M NaCl. Nanocrystalline Mg alloys with hardness greater than commercial alloys were obtained. All the binary alloys showed lower corrosion current densities when compared to milled Mg. Decreased cathodic kinetics with an increase in anodic kinetics was observed with Ge addition. The best set of properties was obtained for Mg-Al alloy. Understanding the effectiveness of added alloying elements will help with the development of future high-strength Mg alloys with lower corrosion rates. |
