Cleaning And De-Greasing Of Metallic Materials By Chemical Methods
(AREA)
Abstract
Improved method for the treatment of surfaces in aluminum parts in preparation for receiving metal coating by an electrolytic deposit, essentially characterized by the fact that the surface of the piece of aluminum is subjected to a process of deoxidation by attack of an acidic medium and to achieve the attack time itself a passive state of the surface aluminum that prevents for a few minutes the presence of a new oxidation being removed the piece of bath treatment and washed to remove all acidic residue and with this remaining moisture from washing the piece is passed to a electrolytic tank in which it is necessary to obtain from the deposit on the piece of the metal nickel copper brass by galvanostegia.
