温度冲击对不同阳极氧化温度SiCP/2A12 复合材料阳极氧化膜开裂行为的影响
|
Abstract:
通过己二酸-硫酸工艺制备了SiCP/A1合金（2A12）复合材料阳极氧化膜，研究了不同阳极氧化温度下（15~35 ℃）制备的SiCP/2A12复合材料阳极氧化膜温度冲击后的开裂行为及耐蚀性能。采用FE-SEM对温度冲击前后SiCP/2A12复合材料阳极氧化膜的微观形貌进行了分析，采用电化学阻抗谱（EIS）研究了冲击前后SiCP/2A12复合材料阳极氧化膜的耐腐蚀性能。结果表明：温度冲击对不同阳极氧化温度制备的SiCP/2A12复合材料阳极氧化膜影响程度不同，随着阳极氧化温度的升高，温度冲击后SiCP/2A12复合材料阳极氧化膜的裂纹密度逐渐增加。阳极氧化温度为25 ℃时，温度冲击后SiCP/2A12复合材料阳极氧化膜耐蚀性最好。SiCP/2A12复合材料阳极氧化膜的耐温度冲击性能优于2A12铝合金氧化膜。 Anodic film on SiCP/Al alloy (2A12) composites was obtained by adipic-sulfuric acid process. The cracking behaviors and corrosion resistance of anodic film on SiCP/2A12 composites which was obtained at different anodized temperature (15-35 ℃) were analyzed after temperature shock.The micro morphology of anodic film on SiCP/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 SiCP/2A12 composites before and after shock. The results show that the effect of temperature shock on anodic film on SiCP/2A12 composites obtained at different anodized temperatures was different.After treating by temperature shock, the crack density of anodic film on SiCP/2A12 composites gradually increases with the anodizing temperature increasing. The corrosion resistance of anodic film on SiCP/2A12 composites after temperature shock obtained at anodized temperature of 25 ℃ is best. The temperature shock resistance performance of anodic film on SiCP/2A12 composites is superior to that of 2A12 aluminium alloy oxidation film. 国家自然科学基金（51271012）
