Abstract
In practical use, it is often observed that the corrosion resistance of light alloys cannot be estimated only by the results of statical corrosion test. Although a number of investigators have studied the problem of corrosion of Al casting alloys, few systematical researches under different conditions have been carried out. In this report, statical and stress corrosion tests were carried out with 5%Mg-Al casting (AC7A), 10%Mg-Al casting (AC7B) and K.S. Seewasser alloys. The results obtained are summarized as follows: (1) AC7B alloy is superior to AC7A and K.S. alloys in the statical corrosion test. (2) When the stress is applied in a corrosive environment, AC7B is more prone to stress-corrosion cracking than AC7A and K.S. alloys. This tendency is promoted by the β-phase precipitation treatment. (3) Cathodic protection is effective for these alloys to prevent the stress-corrosion cracking.
