- the electrolyte additionally contains an aluminum trialkyl compound.
- inventive Electrolyte for coating materials with aluminum-magnesium alloys can be used without the in situ generation of magnesium-organic Complexes in a time and cost intensive conditioning phase is necessary before the actual coating process.
- the magnesium alkyl compound is in one Amount of 0.01 to 10 mol%, preferably 0.1 to 1 mol% based on the Aluminum complex contained in the electrolyte.
- Particularly preferred magnesium alkyl compounds, which are used in the electrolyte are selected from the group MgButyl1,5Octyl0.5, MgButyl1, Oethyl1, 0, Mgsec-Bu1, OnButyl1, 0 or Mixtures thereof.
- the aluminum-organic complex compound and the magnesium alkyl compound may preferably be in an organic solvent.
- the organic solvent is more preferably an aromatic solvent, where solvents such as benzene, toluene or xylene or mixtures the same can be used.
- the above-mentioned magnesium alkyl compounds have the advantage that they are industrially available and can be prepared simply and inexpensively in comparison to the abovementioned magnesium aluminum-ethyl complexes Mg [Al (Et)) 4 ] 2
- the preparation of the electrolyte is carried out according to the following steps. First, the aluminum-organic complex compound of the formula MAIR 4 or a mixture thereof, optionally in combination with aluminum trialkyl submitted. There then takes place the addition of a magnesium-alkyl compound as described above. M and R have the same meaning as described above.
- the addition of the magnesium-alkyl compounds in the preparation of the electrolyte has the advantage that the necessary concentration of magnesium and aluminum can be adjusted directly, so that can be completely dispensed with the above-mentioned conditioning process. Furthermore, it is also possible to add magnesium-alkyl compounds during the coating process in order to maintain the appropriate magnesium concentration desired and necessary for the coating.
- the magnesium-alkyl compounds are added dissolved in a hydrocarbon in a particularly preferred embodiment and the aluminum-alkyl complexes are presented dissolved in an aromatic hydrocarbon.
- the hydrocarbon for the aluminum compound is selected from the group consisting of i-pentane, n-pentane, hexane, n-hexane, heptane, n-heptane, toluene and xylene.
- the electrolyte according to the invention it is possible in one Operation Aluminum-magnesium layers of different concentration sequences of aluminum and magnesium by simple and free choice of the amount of addition of organomagnesium compounds.
- the inventive Electrolyte also has the advantage of good conductivity and throwing power.
- the electrolyte according to the invention makes it possible with indifferent anodes to work in the case of the coating of geometrically complicated shaped Parts are used.
- Indifferent electrodes are those that are in themselves Do not dissolve during the coating process, so not from AI or Mg or their Alloys exist.
- coating with indifferent electrodes must therefore Mg-organic compounds and Al-organic compounds in the electrolyte solution be dosed. In doing so, the corresponding concentration of aluminum-magnesium about the addition amount of organomagnesium compounds and organoaluminum compounds.
- Working with indifferent anodes was in the prior art in situ generation excluded from magnesium-organic complexes in principle, as well as the production of layers of various aluminum-magnesium compositions in one operation. This is also after the above described in situ process with a conditioning step for the preparation the magnesium concentration in the electrolyte is not possible.
- the compounds a) and b) dissolved in an organic solvent.
- Another object of the invention is a method for coating of electrically conductive materials or layers of aluminum-magnesium alloys with the electrolyte according to claims 1-9, wherein during the coating phase, the magnesium alkyl compound according to to the claims 1, 3, 5 and 6 in the desired amount is added to a desired concentration of magnesium to aluminum to obtain or maintain
- Another object of the invention is the use of the invention Electrolytes for the production of layers of aluminum alloys on electrically conductive materials or electrically conductive layers.
- 2nd step 55.4 g of an electrolyte of the following composition: 0.8 K [Al (Et) 4 ] + 0.2 Na [Al (Et) 4 ] + 1.17 Al (Et) 3 + 3.85 Toluene was treated with 2.85 g of BOMAG / toluene solution (about 1.0 mol% based on the electrolyte formulation).
- Anodenmateriel 2 alloy electrodes AIMg25, 55 x 10 x 5mm cathode Hexagon bolt 8.8, M8 x 25
- the deposition was started at a current density of 0.05A / dm 2 . After a few minutes, a light covering on the parts to be coated can be seen. The current density was gradually increased to 3.0A / dm 2 . The deposition was terminated after a current of 1.499mF corresponding to a layer thickness of 5 ⁇ . The layer is bright and silvery. RF analysis of the layer: 26.79% by weight Mg, 73.21% by weight
- the reaction was carried out under protective gas argon.
- 2nd step 60.6 g of an electrolyte of the following composition: 0.8 K [Al (Et) 4 ] + 0.2 Na [Al (Et) 4 ] +1.17 Al (Et) 3 + 3.85 Toluene was mixed with 2.0 ml of BEM / toluene solution (about 0.9 mol% based on the electrolyte formulation). There were obtained about 62 g of an electrolyte.
- the deposition conditions are as in Example 1.
- the deposition was started directly at a current density of 2.0 A / dm 2 and was not changed throughout the electrolysis. There was an immediate bright deposition of Al / Mg.
- the deposition was terminated after a current of 3.38 mF corresponding to a layer thickness of 11 ⁇ . This gives an excellent, very uniform, silvery layer. without recognizable defects.
- the reaction was carried out under argon as a protective gas.
- the BEM / isopentane solution is added to a content of 1.85 mmol / g Mg component used without further pretreatment.
- 2nd step 70.04 g of an electrolyte of the following composition 0.85 K [Al (Et) 4 ] + 0.15 Na [Al (Et) 4 ] + 1.08 Al (Et) 3 + 3.15 toluene were added 0.5 g of BEM / isopentane solution (about 0.8 mol% based on electrolyte formulation).
- the deposition conditions are as described in Example 1.
- the deposition took place at a current density of 1.0 to 3.0 A / dm 2 .
- the deposition was terminated after a current of 6.8 mF corresponding to a layer thickness of 20 ⁇ . This gives a very uniform, silvery layer.
- Conditioning step Starting with a starting current density of 0.05 A / dm 2, electrolyzing was carried out with increasing current density up to the maximum possible value of 1.0 A / dm 2 . After a current volume of 7.20 mF, a matte, gray coating is present with poor scattering power.
- 2nd conditioning step After replacing the cathode was further conditioned at 1.0 to 1.2 A / dm 2 . After an amount of electricity of 7.24 mF, with only slightly improved scattering power, a clearly brightened, in part weak, glossy layer is obtained.
