Aluminum organic electrolytes and method for electrolytic coating with aluminum or aluminum-magnesium-alloys

摘要

Organoaluminum electrolytes and methods for the coating of electrically conductive materials with aluminum or aluminum-magnesium alloys, essentially and preferably consisting of Na[Et3Al-H-AlEt3] for aluminum coating, or of either K[AlEt4] or Na[Et3Al-H-AlEt3] and Na[AlEt4] and trialkylaluminum for alloy coating using solutions of these electrolytes in liquid aromatic hydrocarbons or mixtures thereof with aliphatic mono- or polybasic ethers, such as dimethoxyethane, and using soluble anodes of aluminum or of aluminum and magnesium, or of aluminum-magnesium alloy.
