Aluminiumorganische Elektrolyte und Verfahren zur elektrolytischen Beschichtung mit Aluminium oder Aluminium-Magnesium Legierungen

摘要

The invention relates to aluminium organic electrolytes and to a method for coating electroconductive materials with aluminium or aluminium-magnesium-alloys consisting essentially and preferably of Na[Et3Al-H-AlEt3] in the case of the aluminium coating or of either K[AlEt4] or Na[Et3Al-H-AlEt3] and Na[AlEt4] and trialkylaluminium in the case of the alloy coating. According to the invention, solutions of these electrolytes in liquid aromatic hydrocarbons or mixtures thereof with aliphatic monobasic or polybasic ethers, for example dimethoxiethane, and soluble anodes consisting of aluminium or aluminium and magnesium or an aluminium-magnesium alloy are used.
