Abstract
Metals which are to be coated with a surface layer of phosphate G by treatment with phosphoric acid or a solution of phosphates are subjected to a preliminary treatment by immersion for a period of from a few seconds to a few minutes in a dilute solution of a copper salt, e.g. the sulphate, or a nickel salt, or a solution containing both a copper salt and a nickel salt. The metal may be given a treatment in a solution of a zinc salt prior to the treatment in the copper or nickel salt solution or a zinc salt may be added to the solution of the copper or nickel salt. An electric current is preferably employed to hasten the action, the article being made the cathode. The conditions of the preliminary treatment are such that no definite plating is formed, but the metal is given a smooth surface which improves the adherence of the phosphate coating. When a preliminary treatment in a zinc salt solution is employed a solution containing zinc sulphate, common salt, boric acid, aluminium sulphate, and dextrine may be used. The phosphate coating may be formed by using a bath of phosphoric acid or iron phosphate with or without metallic iron. Other phosphates such as chromium, nickel, or copper phosphate may be added to the bath. After the phosphate coating has been formed the treated metal may be immersed in oil at ordinary or at elevated temperature. According to the first Provisional Specification an electric current may be used during the phosphate treatment and according to the second Provisional Specification the preliminary treatment may comprise the deposition of any metal, e.g. zinc, either by electrolysis or by simple immersion.
