Abstract

The increasing use of weathering steels (WS) has raised concerns regarding the diffuse emission of alloying elements. This research paper investigates the release of iron (Fe) and the alloying elements (Cr), copper (Cu), manganese (Mn) and nickel (Ni) from two commercially available WS at urban field conditions in Stockholm, Sweden, during 1 year and in the laboratory at simulated urban conditions. The amount of released metals is evaluated and compared with recommended levels of metals in drinking water and the formation and evolution of the protective patina is studied in parallel to assess the influence on the metal release process. Only minor amounts of the alloying elements are released and is only linked to the outermost surface composition of the patina during the very beginning of the exposure. The released amounts are found to be lower compared with the corresponding levels recommended by the World Health Organisation for drinking water.

城市大气条件下风化钢的铜绿形成和合金金属的弥散--实验室和实地综合调查
随着耐候钢(WS)使用量的不断增加,合金元素的扩散排放引起了人们的关注。本研究论文调查了两种市售 WS 在瑞典斯德哥尔摩城市实地条件下一年的铁(Fe)和合金元素(Cr)、铜(Cu)、锰(Mn)和镍(Ni)的释放情况,以及在实验室模拟城市条件下的释放情况。对释放的金属量进行了评估,并与饮用水中建议的金属含量进行了比较,同时还对保护层的形成和演变进行了研究,以评估其对金属释放过程的影响。只有少量的合金元素被释放出来,而且只在接触的最初阶段与保护层最外层的表面成分有关。与世界卫生组织推荐的饮用水相应水平相比,释放量较低。
