In the present study, A layer of the modified composite coated surface is made using Copper, molybdenum disulfide, and hexagonal boron nitride. For this process, Electrical discharge machine (EDM) is used but in reverse polarity. Various factors of the machine influenced the thickness of the deposited layer like the amplitude of peak current, duty factor, powder mixing ratio, used etc. For the deposition process, green compacted electrodes which was made after mixing the powder material in mortar for approximately 2.5 hour and post processing in Hot mount press moulding machine. After that the mixture powder was put in the Hot mounting press machine to made green compact electrode with specific parameters. Experiment was performed on EDM and many analysis were carried out to study the morphology of the coated surface. To get the morphology of the coated layer, FESEM images were examined and found the satisfying uniform distribution of deposited layer constituents with material powder mixing ratio of (Cu/HBN/MoS2) at (20/40/40) got with 50% duty factor and 10 Ampere peak current amplitude. Also done XRD, for the evidence of Cu, MoS2 and HBN.
