The present paper studied the experimental investigation on electrical discharge coating of ZE41A magnesium alloy (EDC) with tungsten carbide-copper (WC/Cu) powder metallurgy (PM) electrode. In order to attain the surface characteristics, three parameters were selected such as compaction load, current and pulse on time. Response characteristics such as material transfer rate (MTR) and surface roughness (Ra) were considered in this study. Central composite design in response surface methodology was applied to conduct experiments. Empirical models were developed for MTR and SR. AVOVA test was conducted to identify the most influence parameters. Additionally, optimized parameters were identified by response surface optimizer. It is observed that the current play a vital role in increasing the MTR and minimize the SR of the coated surface followed by compaction load and pulse on time. Various studies such as scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were carried out on the coated surface. Bulk mass deposition and bigger craters were observed in the surface coated with 150 MPa and 3A respectively.

Edm Process

Electrical Discharge Machine (EDM) is the process of designing the material and including complex structure using electrical discharge. Many research has been carried out in the EDM using different materials to increase Material Removal Rate (MRR), decrease Electrode Wear Rate (EWR) and Surface Roughness (SR). The various optimization techniques are applied to identify the parameter settings to increase MRR. In this research, the EDM process is conducted using the material of AZ 31 Magnesium alloy with hydrothermal treatment to reduce the MRR. The Taguchi method is applied to identify the optimal parameter for the EDM process to minimize the MRR, EWR and SR. The optimal value of the method is obtained as peak current of 55 A, voltage of 220 V, pulse on-time of 16 µs, and the pulse off-time of 512 µs.
