Electrochemical Machining of AISI 202 Using Mixed Electrolyte

Several and stiff competitions prevail in manufacturing and marketing industries. It is the trend of the industries to manufacture products that are worthy and long lasting. A new material revolution has become inevitable in this regard. Due to the revolutionary impact, the expansion has been done in the families of difficult-to-machine materials like high carbon, high chromium AISI 262, stainless steel and super alloys.This research work throws light on enhancing performance of the ECM by obtaining an improved Material Removal Rate (MRR) and minimum Surface Roughness (SR) on AISI 202 steel. Traditional aqua solution of NaCl and NaNO3 separately performs the better achievement of MRR and surface roughness.Hence, in this work an attempt is made to explore the impacts of the Silver Nitrate solution (AgNO3) with normalities of N/10 and N/50 mixed with aqua of NaNO3 which leads to improved performance of the ECM process with minimal operating expenses.
