Deformable Counter-Electrode for Homogeneous Electrochemical Treatment

Solution Overview

Problem

Electrochemical finishing methods face challenges in achieving homogeneous surface treatment, particularly for parts with complex geometries, due to the difficulty in controlling current distribution and the need for manual adaptation of counter-electrodes, leading to increased costs and time inefficiencies.

Innovation Solution

A deformable counter-electrode system that automatically adapts to the geometry of conductive parts by immersing an electrode and a deformable counter-electrode in an electrolytic bath, connected to a source of continuous or pulsed current, allowing point-by-point adaptation to ensure homogeneous current distribution without prior knowledge of the part's geometry.
