摘要：
The paper presents the behavior of chrome alloyed steel in various combinations of inorganic media. 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.
