Abstract

Electric Discharge Machining (EDM) is one of the most popular nontraditional machining processes applied for machining very hard conductive materials with desired shape, size and dimensional accuracy. In this paper, copper-coated 6061 aluminium alloy is applied as EDM electrode instead of copper. Electrodeposition, simple and economical process, was used for preparation of copper coating on 6061 Aluminium alloy. The method of anodization was applied in order to get a strong adhesive copper coating on aluminium alloy substrate. Ammonium bi-fluoride (NH4F·HF), a fluorine-containing inorganic substance was added to the anodizing solution to increase the porosity of aluminium alloy surface. The copper-coated surface was characterized with SEM/EDS and XRD. Lower electrode wear, surface roughness and higher MRR were found for copper-coated 6061 Aluminium alloy EDM electrode compare to uncoated 6061 Aluminium alloy electrode.
