ELECTRODEPOSITION CELL

摘要

An electrodeposition cell has a rotating cathode and a scraper for removing deposit from the cathode. The axial extent of the engaging part of the scraper is less than half (for example 1/63) of the axial extent of the electrode, and that part is axially movable to engage any part of the cathode as the cathode rotates. The scraper does not strip bare the surface of the cathode, but leaves a microscopically rough deposit, which improves the deposition rate.
