通过不同的技术手段检查了暴露于氯化物溶液的碳和耐候钢上形成的粘附（AR）（区分为刮擦和撞击）和非粘附（NAR）锈蚀。两种钢的NAR均由最丰富的鳞球石、赤球石和针铁矿组成，而两种钢的AR中还含有最丰富的尖晶石相（磁铁矿/磁铁矿）。报道了两种钢不同锈层中化合物的结晶学、相对数量、物理和化学性质的差异。对于这两种钢，大约21%的腐蚀铁完全转化为附着的铁锈。(c) 2005 Elsevier Ltd版权所有。
Adherent (AR), differentiated as scraped and hit, and non-adherent (NAR) rusts formed on carbon and weathering steels exposed to chloride solutions in total immersion tests were examined by means of different techniques. The NAR for both steels is composed of lepidocrocite, the most abundant, akaganeite, and goethite, whereas the AR in both steels contains additionally a spinel phase (magnetite/maghemite), which is the most abundant. Differences in crystallographic, relative amount, physical and chemical properties of the compounds in the different rust layers on both steels are reported. For both steels around 21% of the corroded iron converts completely into adherent rust. (c) 2005 Elsevier Ltd. All rights reserved.
