“…Carbon steel is a commonly used structural material for architectural and engineering purposes. Corrosion of steel has been addressed through different surface treatments, such as galvanisation with zinc, [27] or using chromate salts, [5] surface silanation, [28] or surface phosphating. [29] Application of organic coatings (i.e.…”

“…The zinc promotes good galvanic protection, behaving like a sacrificial anode [3]. The zinc oxide also creates a barrier that protects the carbon steel from aggressive environments [8]. Among the galvanizing techniques, the use of zinc electroplating stands out [9][10][11][12].…”

Influence of current density and temperature in the zinc electroplating process at sulfate-based acid solution: study on process efficiency and coating morphology

Zinc as a metallic coating is a common strategy to protect the carbon steel against corrosion. The most common process of zinc deposition is known as electroplating. Because of the high toxicity of cyanide-based baths, the interest in acid baths has grown, but they present many challenges to be overcome. Several operational parameters and bath constitution – such as current density, pH, and zinc concentration – can impact the current efficiency, deposit quality, and coating morphology. In this work, the process efficiency and the coating morphology were evaluated on electroplated AISI 1008 carbon steel samples. The current density and temperature were individually varied on a range from 7.5 mA.cm-2 to 30.5 mA.cm-2, and from 40 °C to 60 °C, respectively. The process efficiency was evaluated by current efficiency (eC). The surface morphology was analyzed by both optical microscopy (OM) and scanning electron microscopy (SEM). Varying the bath temperature did not promote impacts in the current efficiency, which remained in all temperatures evaluated over 95%. On the other hand, increasing the current density, increased the current efficiency, starting from (85 ± 2)% at 7.5 mA.cm-2 to (92 ± 2)% at 19.0 mA.cm-2, and (95 ± 1)% at 30.5 mA.cm-2. Through OM and SEM analysis, the increase in the temperature tended to turn the coating rougher, and the sample was not completely covered at 7.5 mA.cm-2. Therefore, we recommend the use of a temperature between 40 °C and 50 °C associated with a current density of 30.5 mA.cm-2.

“…Para tanto, ocorre a imersão de um cátodo metálico (material a ser protegido) e de um ânodo condutivo, em uma solução eletrolítica, onde o íon metálico presente na solução irá depositar-se na superfície do cátodo (ALMEIDA et al, 2019). Comumente são empregados três tipos de banhos no processo de eletrodeposição zinco: os banhos alcalinos contendo cianeto, os banhos alcalinos livres de cianeto e os banhos ácidos (ALSHATER et al, 2019). Na eletrodeposição do zinco, diversos fatores podem afetar a eficiência de corrente, a qualidade do depósito e, consequentemente, a resistência mecânica e à corrosão do material.…”
