摘要

Invention patent: composiu00c7u00e7o aqueous galvanizau00c7u00e7o with zinc nickel alloy and method for deposiu00c7u00e7o a zinc nickel alloy on a substrate.The invention provides a composition, aqueous electroplating with zinc nickel alloy is particularly useful in a method of electroplating for the deposition of a layer of zinc nickel alloy on a substrate, in which the layer exhibits a concentration of nickel deposited uniformly and Bo. The aesthetics in a wide range of current densities.The composition of the coating comprises a composition of electrolyte and an organic composition.In one form, the composition of letru00f3lito comprises a source of zinc ions, a source of ions nu00edque, a pH buffering agent, and at least one additional salt, and the organic composition comprises a polisher of nickel from a nickel polisher class 1, class I I, an aromatic carboxylic acid, a compound of aldeido or ketone, and a non - ionic surfactant or anionic.The composition of the galvanization is particularly free of chelating agents and products of ammonium free.
