摘要：
In this paper, Sb and Sn elements were added to high-strength weathering steel. The corrosion behavior of three kinds of high-strength weathering steels without Sb/Sn, with Sb and Sb + Sn in a simulated industrial atmosphere, was studied. The results show that adding Sb and Sn can accelerate the initial corrosion rate, quickly form a more dense and stable rust layer, and thus reduce the corrosion rate and total corrosion amount in the later period. Sb and Sn are uniformly distributed in the rust layer and play an important role in improving the density of the rust layer. The corrosion resistance of weathering steel is improved after the addition of Sb alone and Sb + Sn combined, and the corrosion resistance is more excellent when the composite is added.
