Abstract:

The report describes a process for electrodepositing lustreless conductive coatings on various alloys of aluminum, steel and copper. Initial work was plating over steel. The emphasis of the internal study was the plating of aluminum alloys. Alloys of aluminum are difficult to plate because of the ever present film of insulating oxide. Special techniques are required to electroplate any metal over aluminum. Aluminum alloys 1100, 6061, 40E, 356 and 380 were successfully plated and met the specific requirements for color, gloss, abrasion resistance, corrosion resistance, adhesion-flexibility and contact resistance. Alloy 2024 was rated fair with regard to adhesion of the plating. Alloy 5052 presented a problem with regard to obtaining adequate nickel adhesion to the alloy. Author
