Device intended for implementing an anodization treatment and anodization treatment

A device for performing anodizing treatment on a part, the device comprising:

• a treatment chamber comprising a part to be treated and a counter-electrode situated facing the part to be treated, the part to be treated constituting a first wall of the treatment chamber and the counter-electrode constituting a wall of the treatment chamber situated facing the first wall;
• a generator, a first terminal of the generator being electrically connected to the part to be treated and a second terminal of the generator being electrically connected to the counter-electrode;
• and
• a system for storing and circulating an electrolyte, the system comprising:
• a storage vessel, different from the treatment chamber, for containing the electrolyte, the treatment chamber having a volume that is less than the volume of the storage vessel;
• and
• a circuit for circulating the electrolyte in order to enable the electrolyte to flow between the storage vessel and the treatment chamber,
• wherein the counter-electrode is arranged not to be immersed in the electrolyte.
