剥蚀
exfoliation corrosion
剥蚀exfoliation eorrosion在沿着平行于材料表面的平面上发生的腐蚀引起的层状剥离。又称层状腐蚀。通常,这种破坏发生在晶界处。由于在那里生成的腐蚀产物容胀产生的张应力,使得一些内面与材料脱开,产生分层剥离的形貌特征。 经过回火处理的某些铝合金轧材,在多种露天环境下,特别是在海洋环境和工业环境条件下,最容易发生剥蚀。例如,可热处理的铝铜系硬铝合金(LY)、锻铝合金(LD)、铝锌镁系超硬铝合金(LC,其中的镁含量)2%),以及可变形硬化的铝镁系防锈铝合金(LF),都对剥蚀表现出不同程度的敏感性。上列铝合金制品,在轧制、锻压后,在它们晶粒的长和宽的方向上,分别得到了高度的伸长和延展,而在晶粒厚的方向上却变得很“薄”。同时,它们的固溶体在沿着晶界的方向上,发生选择性分解,从而使这些合金材料变得对剥蚀和应力腐蚀裂开都相当敏感。热处理虽然能改善这些合金材料对这两种腐蚀破坏的敏感性,但热处理对剥蚀的影响要比对应力腐蚀裂开的影响大得多。与应力腐蚀裂开一样,不能凭借上述铝合金材料对晶间腐蚀耐蚀性的优劣,预测它们对剥蚀耐蚀性的高低。对不能进行热处理的锻材,剥蚀一般是不常见的,即使发生,也不太严重。 由于变形铝合金具有质轻、强度高、工艺性能优异和价格低廉等特性,它们作为一类重要的结构材料,广泛应用于航空、航天、军事装备、海洋和交通运输等工程,以及众多的工业设施与民用建筑中。剥蚀是高强度变形铝合金在腐蚀性环境条件下极具破坏性的重要腐蚀形式之一。因此,无论是铝合金产品的质量控制,或是新型铝合金的研究发展,都必须检验和评估它们耐剥蚀的性能。 国际上通用的检验铝合金剥蚀倾向的标准加速试验方法有两种。①EXCO试验:将试片放在25土3℃,含4M氯化钠、0.5M硝酸钾和0.IM硝酸的溶液中进行腐蚀试验。用于检验铝铜系和铝锌镁系合金的剥蚀倾向。②Asset试验:将试片浸在65士1℃,含1 .OM氯化馁,O.25M硝酸馁、O.olM酒石酸按和0.09M过氧化氢的溶液中24小时,然后将试片与标准图谱对照、评级。用于检验铝镁系合金耐蚀性能。 (杜元龙)
