![عکس صفحه اول مقاله: Atmospheric corrosion resistance of MnCuP weathering steel in simulated environments Atmospheric corrosion resistance of MnCuP weathering steel in simulated environments](/preview/png/1469783.png)
In this work, atmospheric corrosion resistance of low cost MnCuP weathering steel in simulated coastal, industrial, and coastal–industrial atmospheric environments was investigated by wet/dry cyclic acceleration corrosion tests. The results indicate that MnCuP weathering steel exhibits high corrosion resistance in the three atmospheres. Besides, the alloying effect of Mn, Cu, and P elements on the anti-corrosion mechanism of MnCuP weathering steel was discussed by techniques of X-ray photoelectron spectroscopy, potential–pH diagram, and electron probe microanalysis.
► Atmospheric corrosion resistance of a low cost MnCuP weathering steel was investigated by simulated wet/dry cyclic tests.
► The steel shows high corrosion resistance in simulated coastal, industrial, and coastal–industrial atmospheres.
► Mn and Cu are identified in bivalent and univalent respectively, leading to cation-selectivity of the rust layer.
► Phosphorus promotes the formation of non-soluble phosphates that may act as corrosion inhibitor in rust layer.
