Anticorrosion requirements for the metallurgy, automotive, and aeronautical industries have increased in recent years, for which alternative plating chemicals must be developed. This study focuses on obtaining a Zn-Ni alloy plating with higher corrosion resistance and brightness. For this purpose, tetraethylenepentaamine as complexing agent, triethanolamine as the surfactant, and gelatin and [Formula: see text]-aminobenzenesulfonic acid as brightening agents for the plating were selected and their optimal concentrations were determined for applications. The optimal Zn-Ni ratio and plating thickness were analyzed using an X-ray Dal device. Improved plating performance of the Zn-Ni alloys was achieved with a Zn-Ni alloy containing 12–14% Ni.

Copper–nickel alloy has the potential in sustaining the recent demands in advanced marine engineering applications. It has been found advantageous over other copper alloys due to the unique properties and corrosion resistance they possess. However, the structure of Cu–Ni alloy alone is not sufficient to withstand many applications, as the structure cannot perform efficiently in an aggressive environment. The performance of this alloy inherently depends on carefully select alloying compositions, as the alloying elements are associated with the precipitation of intermetallic particles that will enhance mechanical properties and corrosion resistance when designing the component of Cu–Ni alloys. A combination of alloying elements has been conceptualized in the designing of copper–nickel alloy. This review described the role of alloying elements in modifying the microstructural features through phase transformation and how it affects the improvement of the mechanical and physical properties of Cu–Ni based alloys. The effect of alloying elements on the structure and properties of Cu–Ni alloys have been critically summarized based on surveying the works done by authors on this category of structural modification binary Cu–Ni alloy.

The development of alternative coating material is important for the corrosion life of metals. Improving the corrosion resistance and decorative appearance of zinc-nickel coatings is gaining importance. Related physical properties can be provided by using various chemicals. Tetraethylamine, triethanolamine, gelatin, and p-aminobenzenesulfonic are the chemicals used in this study to evaluate corrosion resistance and decorative appearance.

Strong Candidate

Considering the good corrosion resistance of Zn-Ni alloy, it is selected in the present study to be the protective coating on mild steel and it is considered as a strong candidate for the replacement of environmentally hazardous cadmium. Zn-Ni alloy coating is applied by electrodeposition at optimum temperature, current density and time. The bath solution used is consisting of EDTA as complexing agent. The electrodeposition is also carried out with tartaric acid and benzaldehyde additives to have good corrosion resistance and brightness. The electrodeposits obtained with and without additives are examined for nature and alloy composition. The corrosion behaviour of the electrodeposits is studied by Tafel polarization and electrochemical impedance spectroscopy.

Residual Stress Analysis

Zn-Ni-alloy electroplated steels are one of the surface-treated materials with a high corrosion resistance and are mostly used for automobiles. It is said that the corrosion resistance is more than four times as great as that of Zn-plated steels. Concerning x-ray stress measurement, Kyono et al reported the result of measurement on y (552) planes and showed that the sin2φ diagram was severely curved.X-ray stress analysis in surface-treated materials will become more important. Some problems, however, remain to be studied when we apply the x-ray method to thin layers. For example, the effective x-ray penetration depth may be different from that in ordinary materials. And complex gradients of stresses and compositions may exist.
