Electrochemical Discharge Grinding of Chrome Alloyed Steels in Inorganic Solutions

Abstract:

The behavior of chrome alloyed steel in various combinations of inorganic media has been studied. Steel samples were processed by electrochemical discharge grinding in nitrates (KNO₃, NaNO₃), chlorate solution (NaClO₃) and nitrates with various additives (KNO₃+Na₂CO₃, NaNO₃ +NaClO₃). In inorganic solutions, the presence of a great number of negative ions (NO₃^-, ClO₃^- HO^-) resulted by electrolytic dissociation of the salts, increases the metal oxidation as well as anodic dissolution. The rate of metal dissolution increased with the increasing NO₃^- ions that accelerate the anodic dissolution
