A Comparative Study on Surface Structure of Thin Zinc Phosphates Layers Obtained Using Different Deposition Procedures on Steel
نویسندگان
چکیده
The protection of metallic surface is commonly done with zinc phosphate in acid aqueous phosphate solutions containing zinc ions and phosphoric acid, as well in addition of other metallic ions (nickel, chromium, calcium, niobium etc.), in presence of accelerators as nitrate ions, hydroxylamine sulfate, benzotriazole and others. The present article is a study on the surface structure of zinc phosphated layers used as protection against corrosion.
