Abstract

Electrolytic solution for the electrochemical polishing of metal articles which constitute the anode in the polishing process by application of electrical currents. The solution comprises at least one compound of the alkylbenzene sulfonic family of formula (I), its salts or derivatives, where R1 corresponds to an alkyl radical of 10 to 14 carbons; and R2 is selected from a hydrogen atom and an alkyl radical of 10 to 14 carbons. Polishing procedure of metal articles by application of electrical current, the anode being the metal article to polish, characterized in that it comprises at least one stage of interaction of said anode with chemically inert particles with size over 100 microns. Device for said polishing procedure, comprising at least one receptacle divided by a vertical partition wall which defines two vessels interconnected by their lower part, the first of them designed to contain the anode of the electrochemical reaction and provided in its lower part with means of separation permeable to liquid solutions; and the second vessel provided with means of oscillation of the liquid contained in its interior.
