Definitions

  • the invention relates to a system for the electrodeposition of metals, in particular aluminum from aprotic, oxygen-free and water-free, organoaluminum electrolytes, with an aluminum cell for wire, tube and strip material which can be sealed off and acted on with a protective gas.
  • Electrolysis plants for plating wire and strip-shaped materials are known, in which the material to be treated is passed through an electrolysis bath in vertical loops.
  • DE-OS 15 21 076 discloses a device for plating a strand of plastic, in which the conductively precoated plastic strand is passed through an electrolysis bath in a plurality of loops with the aid of drive and contacting rollers arranged at the top and deflection rollers arranged at the bottom vertical anode plates are provided in the electrolysis bath parallel to the course of the strand.
  • Such a system is neither intended nor suitable for the galvanic deposition of aluminum, since an electrolyte must be used for aluminizing, which is produced under oxygen-free and water-free conditions and must be kept as far as practically possible.
  • the electrolytic bath in the galvanic aluminizing must be kept away from air. Such a facility must then be operated in a protective gas atmosphere, the entry and exit of the material to be treated must take place via locks in order to prevent air access to the electrolysis bath as far as possible.
  • the invention is therefore based on the object of creating a system of the type described in the introduction, in which the strip-like strand-like material does not need to be deflected when aluminizing. Another object is that the highest possible deposition rate can be achieved, so that acceptable bath lengths and exposure times result.
  • a tube cell is used as the aluminizing cell, through which the material to be treated can preferably be moved continuously in the axial direction, that at both ends of the tube cell one, on the one hand the penetration of air into the tube cell and on the other hand the Outflow of the electrolyte from the tube cell, preventing lock arrangements are provided.

  • the Joule heat that is increasingly released with the current density can thus be dissipated particularly effectively.
  • T-shaped connecting pieces are arranged between the tube cell and the lock arrangements for masking and deflecting the direction of movement of the flowing electrolyte.
  • the T-shaped connecting pieces should be designed to be as aerodynamic as possible, so that the congestion resistance is as small as possible.
