Electroplating process has been carried out by utilising the Watt’s Bath without brighteners. Plots of weight change of electrodes versus current density shows that weight loss of anodes and weight of deposits on cathodes are proportional to current density and and plating time. While plots of weight change of electrodes versus temperature shows no significant influence of temperature to weight change of electrodes. All plots are compared with theoretical values and shows excellent agreement with Faraday’s Laws. Products that are produced by utilising cast nickel anodes show very good corrosion properties in normal condition, or good appearance without using brighteners. There are 4 parameters involve in this project that are current density, temperature, pH and plating time where the best parameter will get good appearance and ability to corrossion resistance.
