Abstract
A novel process for the electrodeposition of aluminum on metals, metal alloys and on electrically conducting surfaces. More particularly, the invention relates to the electrodeposition of aluminum on metals such as copper, steel, magnesium, titanium, or uranium; on alloys such as bronze and on substances such as carbon, graphite, etc. The invention relates furthermore to novel solutions which serve as baths for the electrodeposition of aluminum from same. Other and further aspects of the present invention will become apparent hereinafter. According to the invention there is provided: 1. An electrolyte for the electrodeposition of aluminum comprising in combination: PA1 A. aluminum bromide; PA1 B. a solvent selected from the group consisting of toluene, and toluene in admixture with other aromatic liquid solvents of aluminum bromide, other than benzene; PA1 C. an additive selected from the group consisting of aromatic hydrocabons having at least two rings; alkylated monocyclic or polycyclic aromatic compounds, aminosubstituted and halosubstituted mono- or polycyclic aromatic compounds, dialkyl aniline, trialkyl amine; PA1 D. Bromides or iodides selected from the group consisting of …
