ABSTRACT
This paper presents the results of a study to assess the effect of the concentration of the solution and the duration of etching in the electrolyte of the optimal composition on the adhesion strength of the iron coating to the metal base. It is established that electrochemical anode etching is the most effective. The maximum adhesion strength of iron deposits to the base is provided by anodic etching in phosphoric-sulfur electrolyte.
Keywords: Iron, metal base, anodic etching, couplings.
