Design of experiment (DOE) help in analyzing data in an efficient manner with fewer trials. The research adopted the method of Genichi Taguchi (G, Taguchi) to study the deposition of a group of binary layers (Zn-Ni), with the influence of four factors (time P, temperature T, corrosion current density I, concentration of nickel chloride salts N) The study of the changes in layer thickness, and the cohesion strength between the layer and the substrate, and the resistance to electrochemical corrosion is represented by the annual rate of corrosion (CR). By using the orthogonal array OA: L18 (21 x 33) and by analyzing the rank and the Signal to Noise Ratio (SNR) in the (Minitab-18). The results indicated that the excessive increase in thickness had a decrease of the cohesion strength and the corrosion resistance, as it was possible to achieve low corrosion rates and good cohesion strength at specific values ​​of the deposition factors, and the study ended with determining the response surface of thickness with the cohesion strength and the corrosion rate.
