Corrosion Behavior of AZ91 Magnesium Alloy
- 1. Korea Institute of Materials Science, Changwon (Korea, Republic of)
Description
One of the barriers limiting wide applications of magnesium alloys to various industries is their poor corrosion resistance. The corrosion properties of AZ91 magnesium alloy, which is the most popular magnesium casting alloy, are affected by microstructural and environmental factors. The corrosion properties of AZ91 magnesium alloy are affected by the corrosion properties of α-Mg and β phases, the volume fraction and distribution of β phase and area ratio of α-Mg/β phases. The corrosion properties of AZ91 magnesium alloy under various environments also change according to the passivity of films and types of corrosion products formed on its surface. The corrosion resistance of the magnesium alloys can be improved by microstructural control through the addition of alloying elements and optimization of the production process
