Abstract

Anodic film on SiC_P/Al alloy (2A12) composites was obtained by adipic-sulfuric acid process. The cracking behaviors and corrosion resistance of anodic film on SiC_P/2A12 composites which was obtained at different anodized temperature (15-35℃) were analyzed after temperature shock. The micro morphology of anodic film on SiC_P/2A12 composites was observed by using FE-SEM before and after temperature shock. Electrochemical impedance spectroscope (EIS) was used to study the corrosion resistance of anodic film on SiC_P/2A12 composites before and after shock. The results show that the effect of temperature shock on anodic film on SiC_P/2A12 composites obtained at different anodized temperatures was different. After treating by temperature shock, the crack density of anodic film on SiC_P/2A12 composites gradually increases with the anodizing temperature increasing. The corrosion resistance of anodic film on SiC_P/2A12 composites after temperature shock obtained at anodized temperature of 25℃ is best. The temperature shock resistance performance of anodic film on SiC_P/2A12 composites is superior to that of 2A12 aluminium alloy oxidation film.
