Corrosion Behavior of ZnAlMg Coating of Dual Phase Steel Sheet

Article Preview

Abstract:

The effect of different composition ratio of ZnAlMg coatings on the corrosion resistance of dual phase steel sheet was experimental studied. The results of neutral salt spray test and corrosion products analysis showed that the three kinds of ZnAlMg coatings have different rust resistance performance. Both the Zn6Al3Mg and Zn13.5Al1.5Mg coatings have high corrosion resistance than the pure Zn coating. The Zn13.5Al1.5Mg coating has better anticorrosion performance than the Zn6Al3Mg coating.
