The coating on Al6061 Aluminium alloy surface with WC/Ni powder compact electrode using electrical discharge machining IJTSRD


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.
