| description | Aluminum has been widely used in industry because of its light weight, high electrical and thermal conductivity, and excellent corrosion resistance. Nickel electroplating process done to enhance the physical and mechanical properties better than the raw material. The objective of this research is to find out the effect of current, time of plating and type of solution to the process of nickel electroplating on hardness, corrosion rate and thickness of nickel layer. Aluminum (Al) was coated with nickel (Ni) variated by current (0.2, 0.3 and 0.4 A), variated by time of plating (10, 15 and 20 minutes) and variated by type of solution (Watts solution and Chloride sulfate solution). Corrosion rate was tested using three-electrode cell method with 0.3 % NaCl solution. Micro Vickers indentation was used for measuring surface hardness using load of 10 grams. A scanning electron microscope was used to measure cross-sectional thickness of Ni layer. The highest value of surface hardness and thickness of layer are obtained on specimens Al/Ni at chloride sulfate solution by the current 0.4 A and plating time 20 minutes. The lowest corrosion rate are obtained on specimens of Al/Ni at watts solution by the current of 0.4 A and plating time of 20 minutes. Increasing current and plating time can improve corrosion resistance and surface hardness of the specimen. The layer thickness of the cross-section of specimen show thin layer on the specimen surface. This layer increase the corrosion resistance and the surface hardness of the specimen. |
