The influence of organic additives in the nickel-plating sulfate electrolyte on the pos sibility of obtaining shiny coatings is investigated. The presence in the structure of the additive of trichloramide fragments and substituents containing a thiocarbonyl group-a residue of thiourea or rubeanoic acid, allows to obtain shiny nickel coatings without the introduction of additional reagents.

Based on chlorex, bis (2-chloroethyl) disubstituted isothiuronium salts containing additional oxygen or nitrogen atoms have been synthesized for amine and thiourea. The resulting salts were studied as gloss-forming additives in the Watts electrolyte for the electrochemical production of shiny nickel coatings. The electrolysis modes that ensure the production of high-quality coatings are found.

The purpose of the work is to review the methods known from the literature and to propose the new methods for preparing the nickel electroplating and nickel electroless plating solutions containing nickel(+2) complexes with 1-hydroxyethane-1,1-diphosphonic acid CH3C(OH)(PO3H2)2 of various proton and stoichiometric composition which allow to obtain high quality nickel coatings. The classification of preparing methods on the basis of chemical reactions nature is given. The advantages and the limitations of each method are discussed. The starting materials are water soluble and water insoluble nickel(+2) salts, nickel(+2) 1-hydroxyethane-1,1-diphosphonates, 1-hydroxyethane-1,1-diphosphonic acid, sodium or potassium 1-hydroxyethane-1,1-diphosphonates. The conclusion is that the methods which base on the use of nickel(+2) bis(1-hydroxyethane-1,1-diphosphonate(1-)) tetrahydrate are the most versatile and convenient. The examples of the preparation of 1-hydroxyethane-1,1-diphosphonate solutions for nickel plating without other substances or with the second ligand (ammonia, ethylenediamine, triethanolamine and others) are given.

Electroplating Process

Electrodeposition of polycrystalline nickel onto carbon steel substrate has been studied from different types of solutions: (bath I) the Watts nickel plating bath, (bath II) the sulfate-chloride nickel plating bath for production of the SUPER Ni coatings, (bath III) the sulfamate nickel plating bath, and (bath IV) the chloride nickel plating bath. A detailed study has been made on the influence of the bath composition on the mass increment and thickness of the deposited Ni coatings. Cathodic current efficiency of the Ni electrodeposition has been also studied. The electrochemical anodic de-plating technique has been used for measuring the thickness of nickel coatings according to ISO 2177:2003. Evaluation of the effect of bath composition on the quality of the galvanic nickel coatings, was carried out using the Hull cell. In a single test, the range of current densities which provided a desired plating characteristic at a given total current, was previewed. Principles of the electroplating process using the Hull cell have also been explained.
