Research on Corrosion Resistance of Mg-Al-Sr Alloy

Abstract:

Article Preview

The corrosion properties of Mg-Al-Sr alloy was characterized with comparison to AZ91D alloy. With the addition of Mg-Sr master alloy, the grain size of Mg alloy refined and the corrosion resistance was improved. The experimental results indicated that the formation of small amount of Al4Sr phase was favorable to improve the corrosion resistance. However, with the increase of Al4Sr stripy phase, the area ratio of cathode to anode will increase, resulting in the decrease of corrosion resistance potential.
