在过去的几十年里,人们为了认识大气腐蚀过程中的因果关系,试图把材料的大气腐蚀失效行为和空气中的腐蚀性组分关联起来;虽然付出了很大的代价,但是进展缓慢。20世纪80年代以后,材料的大气暴露试验和环境因素监测才同时进行。从数据结果来看,材料在不同环境条件下的腐蚀行 In the past few decades, attempts to correlate the atmospheric corrosion failure behavior of materials with the corrosive components of the air in order to understand causality in the atmospheric corrosion process have progressed slowly, albeit with considerable cost. Since the 1980s, atmospheric exposure tests and environmental monitoring of materials have taken place simultaneously. From the data results, the material corrosion under different environmental conditions
