Definitions

This invention relates to the art of treating 7 surfaces of zinc or its alloys in order to provide them with an adherent substantially insoluble coating of phosphates.
the principal objects of the invention are, first, to provide an article having a surface of zinc or its alloys with an improved phosphatic coating of greater uniformity in thickness and color and of greater suitability for the reception and retention of a final finish of paint, varnish, lacquer, japanor other similar organic protective material; second, to provide an improved method for the production of such articles, and, third, to provide improved materials for use in 15 producing such articles.
the invention also contemplates the production of a coating of the character described on articles of zinc' or its alloys which will prevent certain deleterious effects which zinc normally thereto.
a further ob'iect of the invention is to produce a coating of more pleasing character and color.
Stiiianother object is to produce coatings of the character described at a minimum expense and in a minimum of time.
balan in this art should be'kept in mind and is ex- 55 piained as follows. If the solution is to produce has upon organic protectivemateriais applied suit in a coating better adapted to receive and 1 "asused or its bier,
the present invention overcomes all of the diiliculties in prior practice referred to above and, 5 briefly stated, it,involves the discovery that far more satisfactory coatings of the character described can be produced by adding to the treating solutiomin addition to the ingredients already certain compounds; soluble in the solution, which will yield therein the cations of nickel and/or cobalt, the process of the invention consisting in subjecting the zinc surface to the action of a solution containing the negative ions of phosphoric acid as its major anion constituent, zinc ions as its major cation constituent, the cations of nickel and/or cobalt as a minor ionic constituent, and also the nitrate anion as a minor constituent.
Lead also has been proposed, but insofar as I am aware, this is the only metal which has been above hydrogen in the electromotive series.
the metals below hydrogen are deposited at least partially in the metallic state and when present in the coating such metals, of which copper and silver are probably the most typical, all tend to pro-, cute smudgy and non-adherent coatings or else to impair corrosion resistance or paint liie.
Lead is a metal which is so slowly. attachable by weak acids that it also is deposited largely in the metallic state when present in a phosphatic coating bath for zinc, and it is admitted by all those familiar with the art that lead cannot serve as a satisfactory coloring or accelerating agent.
a concentrated stock solution is prepared accordance with the following iormula:
Cobalt as a constituent of solutions of this kind acts very similarly to nickel. ening effect of cobalt is slightly less pronounced It may be substituted practically weight for weight for the nickel, as the two metals have nearly identical equivalent weights. The maximum darkening efl'ect oi the cobalt on the coating is reached atsomewhat less than one equivalent of cobalt to one equivalent oi zinc. However, no advantage seems to be ch- However, the darktained by using either nickel or cobalt in a pro- 1 portion greater than one equivalent of nickel or cobalt to two equivalents of zinc.
This solution can be prepared by suspending the zinc oxide in the water, stirring in the phosphoric acid until clear, and then dissolving therein the cobalt sulphate and sodium nitrate.
This solution may be diluted with water to a 5 to strength by volume'and used hot, like the diluted Formula No. l, to produce coatings on zinc base die castings, galvanized iron, etc.
replenishment of the coating solution as it becomes depleted in strength may not be accomplished indefinitely with Formula No. 2. If this is attempted there will ultimately accumulate in the solution too great a quantity of sodium and sulphate ions.
solutions of the character described maybe used to coat surfaces of zinc or to at least 0.40 equivalent temperature, nature of the metal, etc.
solu-' tions such as the concentrate of Formula No. 1 diluted with water to, say, 20% strength, by volume. However, it may be found more convenient. to use a solution especially prepared for the purpose.
a solution especially well adapted for use in coating such surfaces in the cold, especially when the'solution, is to be applied in a thin film as by brushing, spraying, flowing, etc., has the follow- "ing composition:
the solution is simply appliedto the surface to be coated and allowed to remain until visible action has ceased, which may take from five minutes to half an hour, depending on the prevailing face, after thorough rinsing with clean water, is allowed to dry, when it is ready for painting, etc.
a solution for coating zinc or its alloys comprising the anions of phosphoric and nitric acids and the cations of zinc and of a metal from the group consisting of nickel and cobalt.
a solution for coating zinc or its alloys comprising zinc ions as its major cation constituent, the negative ions of phosphoric acid as its major anion constituent, the cations of a metal of the group consisting of nickel and cobalt as a minor cation constituent, and nitrate anions as a minor anion constituent.
