Multivalent electrolytic process for the surface treatment of non ferrous metallic material

摘要

A process for the electrolytic treatment of non-ferrous metal materials, such as for example magnesium, aluminium, titanium, vanadium and alloys thereof, particularly a process for the production of a surface coating which has both an aesthetic and a protective function.;Said process comprises at least one main treatment stage or anodic stage carried out in a tank or cell, using an alkaline solution which allows the simultaneous treatment of metal materials, even different metals, and/or materials made from alloys and/or combinations and/or other kind of various metals coupled together.;An object of the present invention is also products made from non-ferrous metal materials, provided with surface coatings obtained according to the above process.
