(57) Improved method for applying coatings, generally known as "metallized" surface finishes,
on to component parts adapted to be used as decorative or aesthetical parts on outer
surfaces of transportation means, such as radiator grilles for motor cars. A prior-art
process calls for, after the application of corrosion-inhibiting metal layers, the
application,. again by a galvanic process, of a metal layer adapted to impart the
desired combination of colour and brightness, such as for instance a so-called "gun
barrel" finish. The present invention provides for the addition of a galvanic chromium-plating
phase followed by a phase in which the part is held at a temperature not in excess
of 30°C for at least 24 hours, and then by a further phase in which the same chromium
layer is removed and the more external layer of corrosion-inhibiting metal is activated
in a traditional manner.
