Anti-Corrosion Performance of Cr+6-Free Passivating

Electrogalvanised steel samples (7.5 × 10 × 0.1 cm) were industrially produced and covered with the following conversion treatments:1) blue-colored Cr3+ based pas-sivation; 2) yellow-colored Cr3+ based passivation; 3) green-colored Cr3+ based passivation. For each conver-sion layer, an individual commercial conversion bath was China Hot-Dipped Galvanized Steel Coil/ Dx51d Zinc Coated 1. Zinc Coated Steel Sheet description Special type of steel coil used in different applications within fabrication&manufacturing environments.GI steel coil is a process that involves coating metals such as steel and iron with a thin layer of zinc.The pure zinc layer then turns into zinc oxide when it is exposed to oxygen, and finally zinc carbonate after exposure to carbon dioxide.
