Abstract

A plant and process of electrocolouring aluminium are disclosed. The plant includes an electrocolouring tank, wherein at least one group is arranged which comprises an aluminium electrode located centrally between two counter-electrodes whose mutual distance apart is 80 cm at the most. Each electrode comprises a plurality of elements such as sheet metal strips, plates, pipes, or rods spaced apart from one another and formed from graphite, special cast iron, or stainless steel. The process involves raising the supply voltage to the electrodes up to 16 to 20 Volts, with a programmed intermediate dwell at 8 to 10 Volts, and the use of an electrolytic bath containing stannous salts, silver salts, or copper salts.
