【摘要】 采用大气环境腐蚀检测(ACM)技术研究了几种铝合金材料在室内加速大气腐蚀环境中的腐蚀规律,并考察了腐蚀挂片法和ACM技术之间的相关性。研究表明:ACM技术能够有效地实时测试铝合金材料在加速实验环境中的腐蚀变化特点,且对环境变化具有较高的敏感性;ACM技术和腐蚀挂片法在研究2A12铝合金材质盐雾环境腐蚀时所得结果基本一致,两种测量方法具有良好的相关性。更多还原

【Abstract】 The corrosion behavior of several Al-alloys in an accelerated atmospheric corrosion environment was studied by means of ACM technique, and the correlation between the corrosion coupon method and the ACM technique was also examined. Results show that ACM technique can effectively reveal the corrosion characteristics of Al-alloy in the accelerated test environment and response to environmental changes with very high sensitivity. The results obtained by ACM technology and corrosion coupon method are basically consistent when the corrosion of 2 A12 aluminum alloy is studied in salt spray environment, and the two measurement methods exhibit good correlation.更多还原
