Abstract (en)
The method includes the steps of placing a can body (2) in a cell (21), holding the body (2) in close spaced relationship with a wall (24) of the cell and the can body (2) and thereafter applying a potentialdifference between the can body (2) and the cell wall (24) to teat a surface of the can body. The cell (21) may include a hollow mandrel (25) in close spaced relationship with the inside of the can body (2), through which the electrolyte enters the cell (21). The apparatus may be used to treat the inside, outside or both inside and outside of the can body.
