From this it can be seen that more than three chambers can be used if necessary. The more chambers, the better the protection against diffusion of atmospheric air.
  • the tubular cell 1 and the electrolyte reservoir 12 can expediently be surrounded by a heating jacket in order to obtain higher deposition rates by using a heated electrolyte.
  • Thermometers are preferably attached to both ends of the tubular cell in order to measure temperature differences occurring in the direction of flow and to be able to compensate for them by heating the heating jacket accordingly.
  • the electrolyte can be circulated at any high flow rate via the two T-shaped connecting pieces, so that the current density can be selected to be significantly higher than when the electrolyte is at a standstill, as a result of which higher deposition rates can be achieved.
  • the two T-shaped connecting pieces can advantageously be used for flooding or flushing the tubular cell with a suitable solvent. This takes place with the aid of the inert liquid 26 in the inert storage container 27 after the valves 19 and 20 have been closed and the valves 21 and 22 have been opened with the aid of the circulating pump 25. Since this leads to the chambers 35 and 36, the inert liquid has to be closed via lines 41 and 102 of valve 100 and opening of valve 101 are returned to container 27.

  • Toluene is preferably used as the inert liquid, which can be obtained by distillation from the electrolyte, which consists of toluene dissolved aluminum alkyl complex salt.
  • the disgusting trolyte preferably consists of 3 to 4 mol of inert liquid and 1 mol of aluminum alkyl complex salt, so that the inert liquid toluene can be relatively easily distilled off from the aluminum alkyl complex salt at a boiling point of 110 ° C., with completely oxygen-free and water-free toluene (inert liquid) being obtained as Inert liquid for the preparation of a new electrolyte as well as for use in the container 60 is very well suited.
  • the principle according to the invention can also be used if, for manufacturing reasons, the galvanization does not have to be carried out horizontally but vertically. This is necessary, for example, for the galvanic aluminizing of optical fibers, because on the one hand they can only be drawn using the vertical process and on the other hand they have to be protected immediately after manufacture. It is not possible to deflect or wind up the optical waveguide and then paint or galvanize it in a horizontal position because of its high sensitivity with regard to its mechanical strength.
  • Fig. 3 shows an embodiment of a system for aluminizing in the vertical method in principle.
  • the actual aluminizing cell which is designed as a tubular cell in accordance with FIG. 1, is designated by 103.
  • the strand-like material 105 is guided through the tubular cell 103.
  • T-shaped connecting pieces 106 and 107 are flanged on both sides of the aluminizing cell 103 in order to feed and discharge and redirect the aluminum electrolyte, as indicated by arrows 104.
  • the connecting pieces 106 and 107 are followed by lock arrangements 108 and 109.
  • the lock arrangement 108 contains an inert gas chamber 110, to which an inert gas, for example N 2 , is fed via a feed line 111.
  • the electrolyte 113 and possibly the inert liquid, which may still emerge at the top, can be drained off via a discharge nozzle 112 and fed to the electrolyte reservoir, in accordance with the exemplary embodiment according to FIG. 1 and a drain 117 can be flooded. These two chambers prevent air and moisture from entering the electroplating cell 103.
  • the inert liquid is conducted from bottom to top, as arrows 118 show. They work on the overflow principle.
  • the T-shaped connecting piece 107 is specially designed to prevent the electrolyte 113 from escaping downward through the insertion openings of the strand 105 to be aluminized. This is achieved in that the electrolyte 113 is fed to the aluminizing cell 103 at high speed, the flow being controlled in such a way that a certain negative pressure is created in a tube 119 and is compensated for with inert gas. For this reason, the T-shaped connecting piece 107 is followed by an inert gas chamber 127 of the lock arrangement 109, the inert gas being supplied via a connecting piece 121.
  • the electrolyte 113 which may possibly still escape through the pipe 119 can be discharged via a drainage connection 122 and fed to the electrolyte storage container.
  • the inert gas chamber 120 is adjoined by the two inert liquid chambers 123 and 124, the inflow via a connecting piece 125 and the outflow via a connecting piece 126. These two chambers also work on the overflow principle. Furthermore, a pipe section 127 (for sealing with inert gas) can be under an inert gas pressure via a connecting piece 128.
  • Fig. 4 shows a sluice head in the vertical mode of operation of the galvano-aluminizing system and passage of the material to be treated 129 from top to bottom, as indicated by a broken line.
  • 130 denotes a tubular cell in which there is an electrolyte 131.
  • the tube cell 130 is followed by a lock arrangement 132 which consists of at least three lamellar chambers 133 to 135. These chambers are under an inert gas overpressure which is low compared to the outside atmosphere or 129, depending on the inflow rate of the material to be coated.
  • the chambers 133 to 135 are supplied with inert gas, for example N 2 , via connecting pieces 136 to 141.
  • the chambers 133 to 135 and the inert gas space 142 can be under the same inert gas pressure or advantageously also under an increasing inert gas pressure from the inside out (ie from bottom to top), which results in a Inert gas purging action is created which blows the surface of the product 129 to be coated free of adhering air or contaminant atmosphere and at the same time closes off the galvano-aluminizing system from the outside atmosphere.
  • the inert rinse jet effect can be increased by more than three chambers. However, irrespective of the number of compartments, it can also be reinforced by the fact that the mouths of the compartments are positioned closer to each other towards the outside (still above), so that the flushing jet effect is enhanced. Furthermore, the blowing angle of the rinsing jet can also be changed by a different geometrical design of the chamber walls and its effect can thereby be optimized depending on the coating object surface structure.
  • FIG. 5 shows a discharge head corresponding to the feed head shown in FIG. 4.
  • the same parts are provided with the same reference numerals.
  • At the lower end of the tubular cell 130 there is a narrowing 143 adapted to the cross section of the material 129 to be treated, to which an inert gas lock arrangement 144 is connected.
  • the inert gas lock arrangement 144 like the infeed head according to FIG. 4, consists of at least three lamella-like central chambers 145 to 147, which supply inert gas via connecting pieces (not shown) be hit, as Fig. 5 shows.
  • FIG. 6 shows an embodiment of a discharge head in which the bubbling of inert gas into the tubular cell 130 can be excluded with certainty, the same parts being provided with the same reference numerals as in FIGS. 4 and 5.
  • a space 149 is formed above the constriction 143 by appropriately designing the lower end of the tubular cell 130, and is filled with liquid metal, for example. Gallium, for example, can be used as the liquid metal.
  • the space 149 is shielded from the tubular cell 130 by screens 150.
  • the liquid metal is expediently used for the electrical contacting of the coating object 129.
  • the basic principle of the discharge heads shown in FIGS. 5 and 6 is that the inert gas pressure of the chambers 145 to 147 keeps the electrolyte liquid column in equilibrium so that it cannot run out. This is tied to the narrowest possible outlet orifices for the coating object and requires manometric control of the discharge head.
  • the embodiment according to FIG. 6 has the advantage that electrolyte 131 still adhering to the glavanized material 129 is squeezed out.
