Influence of Silver-Coated Tool Electrode on Electrochemical Micromachining of Incoloy 825

Incoloy 825 alloy is often used in calorifiers, propeller shafts, and tank vehicles owing to the improved resistance aqueous corrosion. The electrochemical micromachining process can be utilized machine such an engineering material higher precision lower tool wear. In present study, investigation was performed enhance of creating micro-holes using silver-coated copper electrodes. sodium nitrate electrolyte under different levels input parameters as voltage, concentration, frequency, duty cycle with a view improving removal rate, conicity, overcut, circularity. It found that electrode had high rate (MRR), better circularity compared uncoated tools most cases, due its corrosive electrical conductivity. From SEM EDS analysis, it observed surface topography obtained while machining process.
