A combined electrolyte for anodizing and copper plating of aluminum and its alloys

A new method for the electrodeposition of copper on oxidized aluminum alloys to form electrolytic coatings exhibiting high performance properties has been discussed. The effect of an azo compound-methyl red (MR)-additive on the structure and physicomechanical properties of the copper coatings formed on oxidized aluminum has been studied. Samples of aluminum alloys AD1M and AMg6BM have been subjected to an anodic treatment under identical conditions in two oxidation electrolytes of different compositions. Copper has been electrodeposited on oxidized aluminum alloy samples using a standard copper plating electrolyte. Comparison with a copper plating electrolyte of an identical composition with an MR azo dye additive has been conducted. The microstructure and adhesive properties of the copper coating formed on oxidized aluminum alloys have been studied. The relationship between the physicomechanical properties of the copper coating (microhardness, open porosity, adhesion) and the action of an azo dye additive in the copper plating electrolyte has been studied. The use of this technology will make it possible not only to increase the reliability and durability of machine parts and mechanisms but also to restore old parts and mechanisms.

“…An excellent adhesive copper coating was achieved by surface preparation of aluminium with anodising solution [11]. Devyatkina et al [12] formulated a combined effective electrolytic bath for both anodising and copper plating of aluminium and its alloy. A fine crystalline structure of deposited copper was achieved by introducing fluorides in electrolytic bath.…”

In this paper, copper based single-wall carbon nanotube (SWCNT) composite was deposited on 6061Al using electrodeposition process. Anodisation method was applied for surface preparation of 6061Al before deposition in order to get strong adherent coating. Ammonium bi-fluoride (NH 4 F•HF) was added to anodised solution for the formation of highly porous structure in 6061Al surface. A stable, well dispersed and colloidal solution was achieved by addition of cationic dispersing agent (CTAB) in the SWCNT mixed copper sulphate electrolytic bath. The microstructure and composition of Cu-SWCNT composite coated surface were inspected by SEM-EDS. The electrical, thermal conductivity and micro-hardness of the Cu-SWCNT composite coated, Cu coated and uncoated 6061Al were investigated. The results show that the electrical, thermal conductivity and micro-hardness were improved by 79, 78 and 39%, respectively, for Cu-SWCNT composited coated 6061Al compared to uncoated 6061Al.
