| الوصف: | The effect of individual and mixed additions of calcium (Ca) and antimony (Sb) on the corrosion behavior of the squeeze-cast AZ91 alloy have been investigated. The corrosion resistance of all modified alloys is better as a result of the refined and reduced volume fraction of the beta-Mg17Al12 phase as well as grain refinement. Individual additions are better than mixed additions. The AZ91-1.0Ca (AZX911) alloy comprising individual Ca addition with a continuous network of the Al2Ca phase reveals the lowest corrosion rate. Among the alloys comprising combined additions, the AZ91-2.0Ca-0.3Sb (AZXY9120) alloy exhibits the best corrosion resistance because of the higher and lower volume fractions of the Al2Ca and Ca2Sb phases, respectively. |
