The use of stainless steel 316L (SS 316L) in the medical, marine, aerospace, bio-medical, and automobile sectors increases rapidly. Electrochemical micro-machining (ECMM) is appropriate method for machining SS due to its burr-free surface, no residual stress, high precision. However, some limitations are found using strong electrolytes, such as HCl, H2SO4, KOH, NaNO3, NaCl, which reportedly fac...
