Definitions
- the invention relates to a device for the electrodeposition of aluminum or aluminum alloys from organometallic electrolytes containing alkylaluminum, said device consisting of a supporting frame with a stand and transportation bearings, at least one plating barrel, at least one drive unit for the plating barrel, and one or more holding arms for the plating barrel.
- Electroplating of small parts and bulk material in aqueous solution is usually effected in rotating, perforated barrels made of polyethylene or polypropylene. These barrels are driven by electric motors arranged in a plastic housing in the supporting rack. Current transfer to the goods mostly is effected by means of flexible copper cords arranged laterally on the barrels and enveloped with a plasticized PVC tube to prevent undesirable epitaxial growth of metal.
- Electrodeposition of aluminum or aluminum alloys from aqueous solutions is not possible due to the very low position of the potential of aluminum. Consequently, electrodeposition must be effected from non-aqueous organic systems.
- electrolytes containing alkylaluminum are used to this end, with organic solvents normally being employed. Therefore, deposition of finely crystalline aluminum and layers of aluminum alloys is achieved in an excellent fashion from anhydrous alkylorganoaluminum electrolyte systems, the alkylaluminum complexes being dissolved in aromatic hydrocarbons such as toluene.
- the plating barrels employed in aqueous electroplating cannot be used in organic electrolyte systems. This is connected with the organic solvents being used and with the operating temperatures of from 90 to 100° C. where such electroplating is carried out. At such temperatures and in the corresponding organic solvents, conventional barrels for aqueous systems are not stable, undergoing decomposition or dissolution, and thus may contaminate the electrolyte. Furthermore, there is a risk of distortion of the barrels to such an extent that mechanical stability is no longer guaranteed.
- the barrel can be opened and closed from outside, and, in order to empty the barrel, a discharge container exposable to inert gas and inert fluid is provided, which is arranged beneath the plating trough and is connected with same via a tube-shaped connector element which can be shut off.
- the invention is based on the object of providing a device for the electrodeposition of aluminum from organic electrolyte systems, in which device the plating barrel is modified in such a way that the plating barrel is stable in the media employed and at the temperatures applied, has a safe drive in flammable media, and nonetheless allows high-quality coating with aluminum or alloys thereof.
- Said object is accomplished by means of a device wherein the drive unit 3 is arranged in an encapsulated gas-tight housing, the plating barrel 13 has a perforated inner tube 15 arranged along the longitudinal axis thereof and open at its side, the lateral openings being arranged directly opposite the electrolyte feed in the electrolyte container, and the plating barrel 13 consisting of a material which is stable both in aqueous and organometallic electrolytes at temperatures up to 110° C.
- the housing case is flooded with an inert gas such as nitrogen or argon and provided with an overpressure of preferably 0.1 to 0.3 bars.
- the housing is also equipped with a feed valve and an overpressure blow-off valve with a nonreturn flap.
- inert gas at a pressure of about 0.1 to 0.2 bars above the set value of the blow-off valve is automatically fed via the feed valve into the drive unit housing on the station.
- the inert gas atmosphere in the drive unit housing is purged, and the overpressure in the housing is reset after each cycle.
- the purging time or the amount of inert purge gas is set via the plant controls.
- the plating barrels are produced from at least glass-fiber reinforced polyphenylene sulfide including a proportion of glass fiber of at least 40%. This ensures chemical stability of the plating barrels at operating temperatures in the electrolyte of up to 110° C., as well as abrasion resistance.
- the drive gearwheels are made of the same material. Another advantage is that this material is also stable in dilute acids and bases, so that pretreatment and secondary treatment of the parts to be electroplated can be effected in aqueous systems such as acids and/or bases in the same barrel without transferring.
- Electrolyte circulation plays an exceptionally important role because, as a result of the limited solubility of organometallic complexes, depletion of metal ions in the liquid boundary layer near the product may rapidly occur in case of insufficient electrolyte circulation. This results in quality losses in the coating of the materials, especially in burning of the materials to be coated, in rough and uneven layers, and possibly even in electrolyte decomposition. In particular, this problem arises in alloy deposition of aluminum, but is also observed in pure aluminum deposition.
- the inventive device in the barrel is equipped with a perforated inner tube which is arranged along the longitudinal axis of the plating barrel and has lateral openings facing the container wall of the electrolyte container.
- the lateral openings of the inner tube are situated directly opposite the electrolyte feed lines in the container wall.
- pumping of fresh electrolyte at high speed through the inner tube and directly to the substrate is accomplished during coating, so that good exchange is ensured and the drawbacks described above are prevented from occurring.
- the holding arms of conventional barrels are mostly rubber-coated and thus unstable in organic electrolytic baths. This also applies to the conventional PVC jackets of electric conductor tracks for the electrolyte current. When using such an arrangement, epitaxial growth of metal on the power supply bars is therefore to be expected.
- the holding arm in the form of a hollow body consists of steel and has a core of polyphenylene sulfide. Arranged in this core of insulating material is the power supply bar for the power supply of electrolysis. It is only inside the barrel where connection between the power supply bar and the contact bulb in the product is made in the bearing of the holding arm.
- the holding arm itself has no electric potential applied thereto and is additionally protected on the outside by a plastic layer coated thereon, preferably one made of PVDF (polyvinylidene fluoride) or of thermoplastic fluorocarbons based on ethylene and chlorotrifluoroethylene.
- PVDF polyvinylidene fluoride
- thermoplastic fluorocarbons based on ethylene and chlorotrifluoroethylene.
- the numeral 1 designates the supporting frame with stand, which includes the single elements of the device, the plating barrel, the drive unit, and the holding arms.
- the supporting frame has transportation bearings 4 arranged thereon which are used to lower or lift the device into or out of the respective electrolyte or rinsing baths.
- the supporting frame has the drive motor 3 encapsulated therein, which is suspended so as to be electrically insulated and has a gas-tight shaft guide 5 .
- a drive gearwheel 6 preferably made of polyphenylene sulfide is arranged at the end of the shaft.
- the drive gearwheels drive the plating barrel 13 which preferably consists of glass-fiber reinforced polyphenylene sulfide.
- the plating barrel 13 is connected with the supporting frame 1 via the holding arms 11 .
- the holding arms 11 are preferably made of stainless steel, they are hollow and coated with fluoropolymers on the outside thereof.
- the hollow space of the holding arms 11 includes an insulating material wherein the power supply bars 9 , 10 for the electrolysis power supply are arranged.
- the numeral 12 designates the bearing block for the plating barrel.
- the plating barrel has perforated side walls 14 and a perforated inner tube 15 which is open at its side.
- An inner auxiliary anode 17 can be introduced into the barrel through this tube so as to achieve higher electrolyte concentrations near the material to be coated.
- the numeral 18 designates the pick-up contacts arranged in the barrel, which preferably consist of copper. Furthermore, flexible current transfer contacts 16 are situated inside the plating barrel.
- the numeral 9 designates the power supply line for the material to be coated, which line is insulated inside the barrel holders.
- the numeral 7 designates the inert gas vent of the drive unit housing, including a nonreturn flap.
- the device according to the invention it is possible to produce high-quality coatings of aluminum or aluminum alloys. Coatings of magnesium and magnesium alloys are also possible, in which case the corresponding alkymagnesium-containing electrolytes are employed.
- the device of the invention is hard-wearing and can also be used in aqueous systems, e.g. in rinsing procedures.
