“…This condition means faster Ni 2+ ions moving in the forward direction from the anode to the cathode and promotes increasing the cathodic current efficiency as the temperature of the electrolyte solution rises. Moreover, the shift to the higher temperature affects nearly equally the deposition of Ni and hydrogen evolution [20].…”

“…A high CCE minimizes energy waste and lowers production costs by ensuring that a sizable amount of the electrical energy supplied to the electrochemical process is used for the intended metal or alloy deposition. A high CCE lessens waste and byproduct creation, decreasing the electrodeposition process's negative environmental effects [50].…”

A new lactate bath was proposed to deposit Co–Cu thin alloy films in nanostructure form onto a steel cathode. The deposition bath contained CuSO4.5H2O, CoSO4.7H2O, CH3CHOHCOOH, and anhydrous Na2SO4 at pH 10. The effects of [Co2+]/[Cu2+] molar ratios, lactate ion concentration, current density (CD), and bath temperature on cathodic polarization, cathodic current efficacy (CCE), composition, and structure of the Co–Cu alloys were investigated. The new bath had a high cathodic current efficiency of 85%, which increased with the applied CD. However, it decreased as the temperature increased. The produced coatings have an atomic percentage of Cu ranging from 19.8 to 99%. The deposition of the Co–Cu alloy belonged to regular codeposition. The Co content of the deposit increased with the amount of Co2+ ions in the bath, lactate concentration, and current density but decreased as the temperature increased. Cobalt hexagonal close-packed (HCP) and copper-rich, face-centered cubic (FCC) Co–Cu phases combine to form the polycrystalline structure of the electrodeposited Co–Cu alloy. The average crystallite size ranges between 46 and 89 nm. Energy dispersive X-ray (EDX) examination confirmed that the deposit contained Cu and Co metals. The throwing power and throwing index of the alkaline lactate bath were evaluated and found to be satisfactory.

“…The major disadvantage of such baths is their toxicity. Various other complexing agents have been used such as sulfamates, tartrates, citrates, glycinates, gluconates and lactates . These complexing agents, especially lactates, are non–toxic, easily obtained and upon degradation the effluents are easier to treat than cyanide …”

A new environmentally friendly electroplating bath for Ni-Cu alloy deposition was developed. Lactic acid was used as a complexing agent. The influence of bath composition, current density, pH and temperature on cathodic polarization, cathodic current efficiency and alloy composition was studied. Different proportions of the two metals were obtained by using different deposition parameters, but at all [Ni 2+ ] / [Cu 2+ ] ratios studied, preferential deposition of Cu occurred and regular co-deposition took place. The Ni content of the deposit increased with Ni 2+ content and current density and decreased with temperature. The surface morphology of the deposited Ni-Cu alloy was investigated using scanning electron microscopy. The crystal structure was examined using the X-ray diffraction technique. The results showed that the deposits consisted of a single solid solution phase with a face-centered cubic structure. The crystallite size lies in the range of 12 to 25 nm for as-plated alloys.
