Abstract
An electrolytic reactor including a conical recess of removable slices through which the electrolyte circulates towards a part to be coated under the action of a pump setting up forced circulation. The part is polarized to act as a cathode, facing a coaxial anode in the recess. This configuration leads to good electrolyte flow in front of the part, allowing accelerated deposit with a uniform thickness of the coating material, and dimensions of the chamber may be added.

An electrolytic reactor for use in a process for electrolytically coating a part, comprising:
- a conical chamber open at two opposite ends;
- a support for the part to be coated, the support being placed in the chamber towards a wide end of the chamber;
- an anode placed in the chamber towards a narrow end of the chamber;
- and
- means for circulating the electrolyte through the chamber from the narrow end to the wide end,
- wherein the chamber includes stacked and removable slices and an armature for supporting and clamping the slices.
