Title: Effect of anionic surfactant on the performance of nickel electroplating watts bath


Muhammad Umar Manzoor graduated in metallurgy & materials Science engineering in 2001 from university of the Punjab, Lahore. In 2008, after completing M.Sc. engineering in metallurgical & materials engineering, he has been awarded Vice Chancellor Research Scholarship (VCRS) scholarship to pursue his PhD studies in university of Ulster, UK. After completing his PhD, he joined COMSATS institute of information technology, Lahore in 2013 as an assistant professor, then joined his parent department, Department of metallurgy & materials engineering, university of the Punjab, Lahore as an assistant professor in 2014. He has also secured British council researchers link travel grant in 2015 to conduct a research project in UK. Beside his own research, he is actively engaged in B.Sc. and M.Sc. final year research projects. The research work has published in numerous national and international peer reviewed journals


Surfactants are an important component in watts bath. In the current study we examined the effect of surfactant in watt bath for nickel electroplating. Dodecyl sulphate salt, an anionic surfactant as wetting agent in the nickel electroplating bath was used to retard the pitting action because of its amphiphilic characteristics. 240gL-1 boric acid and 30gL-1 nickel chloride with different concentration of 5, 15, 30gL-1 at constant temperature was used. Sodium dodecyl sulphate was added into the nickel bath with varying concentration of 0 to 5gL-1. The current density for an hour is 2.5 Adm-2 and Ee is 66oC. To study the thickness of electroplating, optical microscopic method was employed. The quantitative measurement of the adhesion of the nickel plating with the substrate was measured by the heat quench test method following ASTM B571. On different composition of nickel electroplated samples, salt spray test was also performed with 5% NaCl solution of 35oC temperature. Electrochemical corrosion testing was performed for 50gL-1 NaCl solution with a pH of 3.2. The results depict that if the anionic surfactant is increased, the pitting on the substrate is rendered which produces a smooth surface on the electroplated specimen hence it can be concluded that the performance of the nickel electroplating bath is improved by sodium dodecyl sulphate
