An Investigation of Electrodeposited Alloys for Protection of Steel Aircraft Parts
Abstract
Exploratory research was conducted to determine substitutes for Zn and Cd coatings for steel parts of aircraft. Since the coatings had to provide sacrificial (cathodic) protection for SAE 4130 steel and be capable of being electrodeposited, the search was limited to alloys of Cd or Zn and pure Mn and its alloys. Test panels with pure Mn, Mn-Zn and its alloys. Test panels with pure Mn, Mn-Zn-alloy, and Zn-Sn-alloy coatings were exposed concurrently with panels having standard coating of Zn, Cd, and chromated Zn. Cumulative results are tabulated for exposures from 60 to 302 days and from 12 and 20 mo. The pure- Mn and Mn-Zn coating were inferior to the Zn and Cd standards. The Zn-Sn-alloy coatings of 0.3-mil thickness and greater protected the underlying steel as well as the Zn and Cd standards.(See also AD-3775)
