Surface Modification of AI Alloy 2014 by Electrochemical Deposition of Ni

The surface of Aluminum alloy AA 2014 was modified by electrochemical deposition of Ni and its effect on corrosion performance was evaluated. Standard Watt's bath with varying potential, current and time was employed for deposition. The Ni-coated samples were heat treated to improve coating characteristics. Corrosion behavior was studied by electrochemical testing and microstructural characterization was performed using scanning electron microscopy. Microhardness was also undertaken. Experimental results indicate that electrochemical deposition combined with heat treatment can be used to improve the surface properties of Al alloys
