"Accelerated corrosion"（加速腐蚀）是指通过人为控制实验条件，在短时间内模拟材料在自然环境中长期暴露所产生的腐蚀现象。该技术广泛应用于材料科学、工程防护和产品质量评估领域，其核心原理是通过提高腐蚀介质浓度、温度、湿度或施加电化学激励等方式加速腐蚀进程。
在工业实践中，加速腐蚀测试需要遵循国际通用标准。美国材料与试验协会（ASTM）发布的ASTM G85标准规定了改性盐雾试验方法，通过调节氯化钠溶液浓度和pH值加速金属腐蚀。中国国家标准GB/T 19292.4-2019则基于ISO 9223标准，建立了大气腐蚀性的分类评估体系，为加速腐蚀试验提供环境参数基准。
值得注意的是，美国腐蚀工程师协会（NACE）在《材料性能》期刊中指出，有效的加速腐蚀试验必须满足三个相关性原则：腐蚀机理、动力学过程和产物形态均需与自然腐蚀保持一致。例如汽车行业进行的循环腐蚀试验（CCT），通过交替模拟干湿环境，能在200小时内重现车辆零部件2-5年的实际腐蚀效果。
“Accelerated corrosion”是材料科学和工程领域的专业术语，指通过人为控制环境条件（如温度、湿度、化学介质浓度等），加速材料腐蚀过程的实验方法或现象。以下是详细解释：
