Hot Dipped Zn-Al-Mg-Cu Coating with Improved

Zn-Al-Mg coating are still a challenge in this field.According to Cervantes [21],the presence of Cu can improve the wear resistance of Zn-Al coating.Therefore,trace amount of Cu was added to the coatings in this study.The present work aims to study the effect of Mg on the microstructure and corrosion properties of hot dipped Zn-Al-Mg-Cu Study on the Corrosion Mechanism of Zn-5Al-0.5Mg-0.08Si XRD test results showed that the corrosion product of Zn-5Al-0.5Mg-0.08Si alloy coating was almost Zn 5 (OH) 8 C1 2 H 2 O.The features of Zn 5 (OH) 8 C1 2 H 2 O are low electric conductivity,insolubility and good adhesion.The corrosion resistance of alloy-coated steels was detected by neutral salt spray test.Supply Z275 Zn-Al-Mg alloys Superdyma Zinc Steel Z275 Zn-Al-Mg alloys Superdyma Zinc Steel Magnesium Coated Steel Sheet in Coil Manufacturers Factory.We accept OEM custom products all made in China.
