Definitions
- the invention relates to a device for the galvanic deposition of aluminum or aluminum alloys from organometallic aluminum alkyl-containing electrolytes consisting of a support frame with a support bracket and transport receptacles, at least one electroplating drum, at least one drive unit for the electroplating drum and one or more support arms for the electroplating drum.
- the galvanic coating of small parts and bulk goods in aqueous solution such as B. nickel plating or galvanizing usually takes place in rotating, perforated drums made of polyethylene or polypropylene. These drums are driven by means of electric motors which are arranged in a plastic housing in the support frame 5. The electricity is usually transferred to the goods to be coated by means of flexible copper strands, which are arranged on the side of the drums and are covered by a soft PVC hose to prevent undesired growth of metal.
- Galvanic deposition of aluminum or aluminum alloys is not possible due to the very low potential location of aluminum from aqueous solutions. It is therefore necessary to carry out the galvanic deposition from non-aqueous organic systems.
- electrolytes containing aluminum alkyl are used in particular. Organic solvents are usually used.
- the deposition of fine-crystalline, smooth aluminum and aluminum alloy layers is therefore an outstanding success from anhydrous aluminum alkyl organic electrolyte systems, the aluminum alkyl complexes being dissolved in aromatic hydrocarbons such as toluene.
- the electroplating drums used in aqueous electroplating cannot be used in organic electrolyte systems. This is related to the organic solvents used and the operating temperatures of 90 to 100 ° C at which this electroplating is carried out. At these temperatures The usual drums for aqueous systems are not stable at temperatures and in the corresponding organic solvents. They disintegrate or dissolve and can therefore contaminate the electrolytes. There is still the risk that the drums will warp so much that the mechanical stabilization
- the drum o can be opened and closed from the outside, and a drain container to which inert gas and inert liquid can be applied is provided for emptying the drum, which is arranged below the electroplating trough and communicates with it via a lockable tubular connecting piece.
- the invention has for its object to provide a device for the galvanic deposition of aluminum from organic electrolyte systems, in which the electroplating drum is modified so that it is stable in the media used and at the temperatures used, via a secure attachment drive in combustible media and still enables a high-quality coating with aluminum or its alloys.
- the drive unit 3 is arranged in an encapsulated gastight housing
- the electroplating drum 13 has a perforated inner tube 15 which is arranged along its longitudinal axis and is opened laterally, the lateral openings being directly opposite the Electrolyte feed are arranged in the electrolyte container, and wherein the electroplating drum 13 consists of a material which is stable in both aqueous and in organometallic electrolytes at temperatures up to 110 ° C.
- the drive of the drum in flammable liquids is made considerably safer.
- the box is preferably made of stainless steel and the drive shaft for the drum is guided through the housing wall by means of a gas-tight shaft bushing with a seal, preferably made of polytetrafluoroethylene.
- the housing box is flooded with inert gas such as nitrogen or argon and provided with an overpressure of preferably 0.1 to 0.3 bar.
- inert gas such as nitrogen or argon
- the housing is also equipped with a filling valve and a pressure relief valve with a check valve.
- inert gas is automatically fed into the housing of the drive unit via the 5 filling valve at a pressure that is approximately 0.1 to 0.2 bar above the set value of the drain valve.
- the inert gas atmosphere in the housing of the drive unit is flushed after each coating process and the overpressure in the housing is reset after each cycle.
- the purging time or the amount of inert gas is determined via the system control.
- the electroplating drums are preferably made of at least glass fiber reinforced polyphenylene sulfide with a glass fiber content of at least 40%. This ensures the chemical resistance of the electroplating drums o at operating temperatures in the electrolyte up to 110 ° C as well as the abrasion resistance.
- the drive gears are also made from this material.
- An additional advantage is that the material is resistant even in dilute acids and alkalis, so that the pretreatment and aftertreatment of the parts to be galvanized can take place in aqueous systems, such as acids and / or alkalis, without decanting in the same drum.
- Equipping the electroplating drum with a perforated inner tube leads to an improvement in the electrolyte circulation.
- the electrolyte circulation plays an extremely important role, since due to the limited solubility of the organometallic complexes, if the electrolyte is insufficiently circulated, metal ion depletion can very quickly occur in the liquid boundary layer on the product. This leads to qualitative losses in the coating of the materials, in particular to the burning of the materials to be coated, rough and uneven layers and possibly even to electrolyte decomposition. This problem occurs particularly with the alloy deposition of aluminum, but is also observed with pure aluminum deposition.
- the device according to the invention is equipped in the drum with a perforated inner tube which is arranged along the longitudinal axis of the electroplating drum and has lateral openings to the container wall of the electrolyte container.
- the lateral openings of this inner tube are located directly opposite one another the electrolyte feed lines in the tank wall. This ensures that fresh electrolyte is pumped directly through the inner tube to the coating material at high speed during the coating, so that a good exchange is ensured and the disadvantages described above cannot occur 5.
- the support arms of conventional drums are usually rubberized and therefore not resistant in organic electrolyte baths. This also applies to the usual PVC sheathing of the conductor tracks for the electrolyte current. When using such an arrangement, metal growth on the conductor rails can therefore be expected.
- the support arm being made of steel as a hollow body, with a core made of polyphenylene sulfide.
- the busbar for the electrolysis current is arranged in this core of insulation material. It is only inside the drum that the connection between the conductor rail and the contact bulb in the goods is made in the bearing of the support arm. This type of construction eliminates the need to additionally protect the conductor rail against undesired growth of metal.
- the arm itself is not at the electrical potential and is additionally protected on the outside by an applied plastic layer, preferably made of PVDF (polyvinylidene fluoride) or thermoplastic fluorocarbons based on ethylene and chlorotrifluoroethylene. 5
- FIG. 1 is intended to explain the invention in more detail.
- the number 1 denotes the support frame with a support frame, which contains the individual elements of the device, the electroplating drum, the drive unit and the support arms.
- Transport receptacles 4 are arranged on the support frame and are used for lowering or lifting the device into the respective electrolyte or rinsing baths.
- the encapsulated drive motor 3 is arranged in the support frame and is suspended in an electrically insulated manner and has a gas-tight shaft feed 5. At the end a drive gear 6 is arranged on the shaft, which preferably consists of polyphenylene sulfide.
- the electroplating drum 13, which preferably consists of glass fiber reinforced polyphenylene sulfide, is driven via these drive gearwheels.
- the electroplating drum 13 is connected to the support arm 11 via the support arms 11.
- the support arms 11 are preferably made of stainless steel, are hollow and coated on the outside with fluorine-containing polymers. In the cavity of the support arms 11 there is insulation material in which the busbars for the electrolysis current are arranged 9, 10.
- the number 12 denotes the bearing block for the electroplating drum.
- the electroplating drum has perforated side walls 14 and a perforated inner tube 15 which is open on the side. An inner auxiliary anode 17 can preferably be introduced through this tube into the drum in order to achieve higher electrolyte concentrations on the coating material.
- the number 18 designates the removal contacts arranged in the drum, which preferably consist of copper. 5
- Flexible power transmission contacts 16 are also located inside the electroplating drum.
- the number 9 designates the power supply line for the coating material. This is insulated inside the drum holder.
- the number 7 designates the inert gas venting of the housing of the drive unit with a check valve.
- the device according to the invention With the device according to the invention, high-quality coatings with aluminum or aluminum alloys can be carried out. 5 coatings with magnesium and magnesium alloys are also possible, in which case the corresponding magnesium alkyl-containing electrolytes are used.
- the device according to the invention is long-lasting and can also be used in aqueous systems, for example for rinsing processes.
