ELECTROLYTE FOR ELECTROCHEMICAL DIMENSION WORKING Russian patent published in 1998 - IPC

Abstract RU 2119413 C1

FIELD: machine engineering, aviation industry, possibly electrochemical dimension working of refractory nickel-chrome alloys. SUBSTANCE: electrolyte contains sodium chloride (NaCl)-15%, sodium nitride (NaN(NaNO3))-7%, triethanolamine (((HOC2H4)3N)) - 1%, barium nitride (Ba(Ba(NO3)2))-0.5%, water -76.5%. EFFECT: reduced toxicity of electrolyte due to using solution having no hexavalent chrome without deterioration of surface quality. 3 tbl, 1 exp, 2 dwg
