OCMPREHENSIVE ACCELERATED TESTS FOR SIMULATION OF ATMOSPHERIC CORROSION OF ALUMINUM ALLOYS
铝合金大气腐蚀综合加速试验方法的研究

Comprehensive environmental tests(CET) for simulation of atmospheric corrosion of aluminum alloys were carried out by electrochemical and scanning electron microscopy(SEM) techniques.The difference between CET and continuous salt spray test(CSST) was also compared.Results showed that,raining/spray comprehensive test can simulate dry/wet features and also the electrochemical process in atmospheric corrosion.Meanwhile,corrosion morphology and kinetics characteristics of aluminum alloys may be simulated by raining/spray test.It follows that raining/spray test provides better simulation for atmospheric corrosion of aluminum alloys.
