【 摘 要 】

Metal coating process is a lot of choices to improve the quality of materials from metals and non-metals. This is due to the metal coating process, the quality of the material can be maintained both in terms of quality and glossiness. Metal or electroplating coating processes are also used for protection against corrosion attacks and for decorative purposes. The purpose of this study is to determine the effect of immersion time, voltage, and distance of the electrode on the work piece layer thickness and glossiness resulting from metal coating. While the benefits of this study as a reference material for coating methods with various process variables by industry parties engaged in metal coating with electroplating techniques. The research variables are time: 15; 20; and 25 minutes, Voltage: 3; 4.5; and 6 volts, and the electrode distance: 10; 15; and 20 cm, other variables were made constant. The work piece used was made of steel metal the size of the plate size = 200 × 30 × 5 mm3 totalling 54 pieces. The research method used was an experiment with a 3 × 3 × 3 research design. The results of the study can be concluded that the longer the immersion time, the greater the voltage; and the closer the anode-cathode distance, it will affect the thicker the work piece surface layer resulting from metal coating. The smallest thickness of the surface layer was 4.5 um to the largest 10.1 um. In addition, the greater the thickness of the work piece surface layer as a result of metal coating, the greater the number of glossiness. The smallest glossiness number was 125 lux and the biggest glossiness number was 152 lux.
