Improvements in the pre-treatment of aluminum parts whose surface must be protected and galvanically beautified, essentially consisting of chemical attack, bathing in caustic soda solution and at a certain temperature, to open and slightly deepen the surface pores of aluminum; this initial corrosión is cut by a vigorous wash with cold water; undergoing a new attack with an aqueous solution of soda and zinc sulphate, at the same temperature, washed again thoroughly; the piece thus prepared is then subjected to a normal electrolytic bath of chromed or nickel plated.
