ZINC PLATING OF/-METALS A RESEARCH PROJECT PRE'SENTED TO THE CItEMrCAL ENGINEERING DEPARTMENT

Abstract

This research project gives a clear view of the fundamental aspect of electroplating process. It shows how zinc plating serves as a corrosion resistance and decorative plating metal which was carried out using pure zinc anodes. To achieve this experiment was carried out at room temperature with proper agitation of the electrolyte. The variation of voltage and plating time brings about an increase in weight (g) of the metal and the thickness (Y). the value of these parameters were observed. A regression equation was obtained to establish the highest voltage and time required for the appearance of the electroplated metals which is Y = -1.115E-05 - 1.009E-06X1+ 2.02E-06X2 The confidence of this equation is 95%, and the coefficient of regression R2 was calculated to be 0.9906395, close to 1.0, thus means that the regression equation model best represent the experimental data.
