| Abstract: | The research progress of weathering steels and the effect of alloying elements on their atmospheric corrosion resistance were summarized in the present paper.The mechanisms of the effect of Ca-Ni、Ca-Si alloying additions on corrosion resistance of weathering steels were also introduced as well.It was believed that the excellent corrosion resistance of weathering steels was mainly dependent upon the formation of a dense and stable surface rust scale. However,it generally takes a long time (sometimes in excess of 10 years) to develop the protective rust scale in natural environment.The liquid rust will flow and distribute everywhere in the initial period of exposure and pollute the surroundings. Moreover,stable protective scales are very difficult to form in marine environments containing Cl- ions.Aimed at this problem,several new rust scale stabilizing surface treatment techniques were introduced.And also the prospect tendency of weathering steel development was concluded. |
