“…Zn-Ni alloy has been widely applied as high corrosion resistant coating, especially in automobile industry [11,12]. Nano-␣-Al 2 O 3 has been used extensively in metal matrix composite coatings because of its high microhardness, wear resistance and excellent chemical stability [13][14][15].…”

“…Usually the mechanical and chemical properties of metals are improved by alloying. The electrodeposition of Zn-Ni alloys is interesting, because these alloys exhibit a significant higher corrosion resistance and better surface morphology than pure zinc [4][5][6][7][8]. The aeronautical industry has shown increasing interest in Zn-Ni alloy coating as a substitute for toxic and high-cost cadmium coatings [9].…”

The electrodeposition of Zn-Ni alloy from chloride bath was carried out in presence of condensation product (CP) formed between vanillin and hexamine. The investigation of electrodeposition and nucleation process was carried out on glassy carbon electrode using cyclic voltammetric and chronoamperometric techniques. During the anodic scan of cyclic voltammetry, three anodic peaks were observed corresponding to the dissolution of zinc and nickel from different phases of Zn-Ni alloy. The model of Scharifker and Hills was used to analyze the current transients and it revealed that Zn-Ni electrocrystallization process in the presence of CP, under the studied conditions, is governed by three-dimensional nucleation process controlled by diffusion. In presence of CP, the results indicated that nucleation process changes from progressive to instantaneous when the deposition potential becomes more negative. The phase structure and surface morphology of the deposits were characterized by means of X-ray diffraction analysis and Scanning electron microscopy, respectively.

“…The mechanism of electrolytic Zn-Ni alloy deposition has been thoroughly investigated in sulphate [1,2], chloride [3,11,12,18], and sulphate-chloride plating solutions and only a few reports are available for acetate-sulphate and acetate-cloride plating solutions [17][18][19][20].…”

The phase composition of Zn-Ni alloys electrodeposited from acetate-chloride plating solutions containing Zn ?2 and Ni ?2 ions at ratio of 1-12.8 at 50°C was investigated by the potentiodynamic stripping method. Two anodic current density (i a ) peaks emerged in potentiodynamic stripping curves (PDC) at E \ 0.0 V and E [ 0.0 V (vs. Ag/AgCl/KCl sat ), that were attributed to oxidation of certain phases of the Zn-Ni alloy. The ratio of these phases in deposited Zn-Ni alloys under potentiodynamic conditions was affected by the potential sweep rate (m) and maximum cathodic current density (i c ) The ratio of Zn and Ni in certain phases of Zn-Ni alloy was determined by the partial potentiodynamic stripping technique. Experimental data show that Zn-Ni alloy, containing 6.5 at.% Zn and 93.5 at.% Ni and dissolved in i a peak H (E [ 0.0 V), provides the black coloration of the Zn-Ni alloy.
