Definitions
- the invention relates to an electrolyte for the electrodeposition of aluminum-magnesium alloys containing at least one organoaluminum complex compound and a magnesium alkyl compound. 5 Further objects of the invention are a method for producing the electrolyte, a coating method, the use of the electrolyte and an electrolysis kit.
- Magnesium-aluminum-organic complex compounds have recently been used for the electrolytic deposition of aluminum-magnesium alloys. This is described in WO 00/32847 A1. Interest in the electrolytic coating of metal workpieces with aluminum-magnesium alloys has increased significantly due to the excellent corrosion protection provided by the aluminum-magnesium layers and their ecological harmlessness. For this reason, electroplating with magnesium-15 aluminum-organic electrolytes, which takes place in closed systems at temperatures in the range of 60 - 150 ° C, has gained great technical importance.
- MAIR 4 complex compounds of the general type MAIR 4 and mixtures thereof in combination with aluminum alkylene AIR 3 have been proposed as particularly suitable eleldrolytes. These are used in the form of their solutions in liquid, aromatic hydrocarbons.
- M can be an alkali metal such as sodium, potassium, rubidium and cesium, R are alkyl radicals with preferably one, two or four carbon atoms.
- the systems known hitherto are characterized in that the required magnesium-organic complex compounds are initially not available in the electrolyte and only have to be generated in a trochemically complex manner when the electrolyte is used in situ. So ready-to-use start only organic aluminum compounds but no magnesium compounds.
- the above-mentioned magnesium-free starting electrolyte is first filled into the electrolysis cells suitable for coating.
- the required organic magnesium complex is then generated electrochemically by applying a current using separate aluminum and magnesium anodes or an aluminum-magnesium mixed electrode until the concentration of magnesium complex in the electrolyte required for coating is reached.
- the technical object of the invention is therefore to provide an electrolyte which can be produced as simply, efficiently and inexpensively as possible, which enables the aluminum-magnesium coating process to be introduced commercially and the conditioning phase mentioned above for formation of organic Mg complexes no longer necessary.
- an electrolyte for the electrodeposition of aluminum-magnesium alloys containing at least one aluminum-organic complex compound of the formula MAIR4 or mixtures thereof and a magnesium alkyl compound, where M is sodium, potassium, rubidium or cesium and R is a C1-C1 0 alkyl group, preferably a C 1 -C 4 -alkyl group.
- the electrolyte additionally contains an aluminum trialkyl compound.
- the electrolyte according to the invention can be used for coating materials with aluminum-magnesium alloys without the in-situ generation of magnesium-organic complexes in a time-consuming and cost-intensive conditioning phase before actual coating process is necessary.
- the magnesium alkyl compound is preferably in one
- Particularly preferred magnesium alkyl compounds which are used in the electrolyte are selected from the group MgButyl1, 5Octyl0.5, MgButyl1.0Ethyl1, 0, Mgsec-Bu1, 0nButyl1, O or mixtures thereof.
- Alkyl compounds can preferably be present in an organic solvent.
- the organic solvent is particularly preferably an aromatic solvent, and solvents such as benzene, toluene or xylene or mixtures thereof can be used here.
- the magnesium alkyl compounds mentioned have the advantage that they are industrially accessible and can be produced easily and inexpensively compared to the magnesium aluminum-ethyl complexes mentioned above Mg [Al (Et)) 4 ] 2 Electrolytes are made according to the following steps. First, the aluminum-organic complex compound of the formula MAIR4 or a mixture thereof, if appropriate in combination with aluminum trialkyl, is initially introduced. A magnesium alkyl compound is then added as described above. M and R have the same meaning as described above.
- the metering of the magnesium-alkyl compounds in the manufacture of the electrolyte has the advantage that the necessary concentration of magnesium and aluminum can be set directly, so that the conditioning process described above can be completely dispensed with. It is also possible to add magnesium-alkyl compounds during the coating process in order to maintain the corresponding magnesium concentration which is desired and necessary for the coating.
- the magnesium-alkyl compounds are added in solution in a hydrocarbon and the aluminum-alkyl complexes are initially introduced in solution in an aromatic hydrocarbon.
- the hydrocarbon for the aluminum compound is selected from the group i-pentane, n-pentane, hexane, n-hexane, heptane, n-heptane, toluene and xylene.
- Aluminum-magnesium layers of different concentration sequences of aluminum and magnesium by simply and freely choosing the amount of added magnesium-organic compounds.
- the corresponding concentration of aluminum-magnesium is determined by the amount added set of magnesium-organic compounds.
- the electrolyte according to the invention also has the advantage of good conductivity and scatterability.
- the electrolyte according to the invention makes it possible to work with indifferent anodes which are used in the coating of geometrically complex shaped parts.
- Indifferent electrodes are those that do not dissolve during the coating process, i.e. do not consist of Al or Mg or their alloys.
- Mg-organic compounds and Al-organic compounds must therefore be added to the electrolyte solution.
- the corresponding concentration of aluminum-magnesium is set via the amount of magnesium-organic compounds and aluminum-organic compounds added.
- Working with indifferent anodes was previously ruled out for the in-situ generation of organic magnesium complexes, as was the generation of layers of different aluminum-magnesium compositions in one operation. This is also not possible using the in-situ method described above with a conditioning step to produce the magnesium concentration in the electrolyte.
- Another object of the invention is an electrolysis kit for the electrodeposition of aluminum-magnesium alloys on electrically conductive materials or electrically conductive layers, comprising: a) the aluminum-organic complex compounds described above, or aluminum-alkyl compounds of claims 1-3 and 1, 3, 5, 6 and b) a magnesium alkyl compound according to claims 1, 3, 5, 6.
- the compounds a) and b) are dissolved in an organic solvent.
- Another object of the invention is a method for coating electrically conductive materials or layers with aluminum-magnesium alloys with the electrolyte according to claims 1-9, wherein during the coating phase, the magnesium-alkyl compound according to claims 1, 3, 5 and 6 is metered in in the desired amount in order to obtain or maintain a desired concentration of magnesium to aluminum
- Another object of the invention is the use of the electrolyte according to the invention for the production of layers of aluminum alloys on electrically conductive materials or electrically conductive layers.
- Step 1 The BOMAG ® / heptane solution was adjusted to a content of 0.32 mmol / g after the heptane had been condensed with toluene.
- 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 g of BOMAG / toluene solution were added to 3.85 toluene (approx. 1.0 mol% based on the electrolyte formulation). About 58 g of an electrolyte were obtained.
- Anode material 2 alloy electrodes AIMg25, 55 x 10 x 5mm
- Cathode pretreatment degreasing, descaling in an ultrasonic bath with 8% HCI, H 2 O washing, vacuum drying, argon storage.
- the deposition was started with a current density of 0.05A / dm 2 b. After a few minutes, a light covering can be seen on the parts to be coated. The current density was gradually increased to 3.0 Vdm 2 . The deposition was terminated after a current of 1.499mF corresponding to a layer thickness of 5 ⁇ . The layer is light and silvery.
- Step 1 The BEM / heptane solution was after the condensation of
- 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 were mixed with 2.0 ml BEM / toluene solution (about 0.9 mol% based on the electrolyte formulation). About 62 g of an electrolyte were obtained.
- the deposition conditions are as in Example 1.
- the deposition was started directly with a current density of 2.0 A / dm 2 and was not changed during the entire electrolysis. There was an immediate bright separation of Al / Mg.
- the deposition was ended after a current of 3.38 mF corresponding to a layer thickness of 11 ⁇ . An excellent, very uniform, silvery layer is obtained, without any visible defects.
- Step 1 The BEM / isopentane solution is containing
- 2nd step 70.04 g of an electrolyte of the following composition 0.85 K [Al (Et) 4 ] + 0.15 Na [Al (Et)] + 1.08 Al (Et) 3 + 3, 15 toluene were mixed with 0.5 g BEM / isopentane solution (approx. 0.8 mol% based on the electrolyte formulation).
- 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 ⁇ . A very uniform, silvery layer is obtained.
- the electrolyte is conditioned and ready for use only after this process.
