Surface modification by EDM using Co-Cr sintered powder metallurgy electrode

In this investigation, the powder metallurgy (PM) electrode developed from cobalt (Co)and chromium (Cr) powders was used in electrical discharge machining (EDM). This new Co-Cr sintered electrode was used to machine mild steel workpiece with kerosene dielectric fluid. The main objective is to modif...
