Abstract :
EDM is an unconventional machining process widely used for machining tough material. A special aspect of EDM is surface modification by transferring the tool electrode material to workpiece surface. In the present work, electrode prepared with tungsten carbide WC and nickel Ni by powder metallurgy route as tool and Al6061 as workpiece substrate. By changing the polarity of EDM workpiece as cathode and tool as anode , the hard carbide layer of WC Ni tool has been deposited on the workpiece. The influence of compaction load through P M method, discharge current and pulse on time during electrical discharge coating EDC on metal transfer rate MTR and tool wear rate TWR have been studied. As design of experiment, face centered central composite of response surface methodology RSM has been adopted to study the influence of various parameter on EDC.
