Abstract:

Coating materials are needed to replace electrodeposited cadmium on steel fasteners for use in high performance aircraft. A study was made to compare corrosion resistance of ten experimental coatings, mostly aluminum-rich types, with cadmium. Several experimental coatings provided high resistance to 5 NaCl salt fog and NaCl-SO2 salt fog exposure tests. Paint adhesion was excellent on all fastener coatings with an epoxy primerpolyurethane topcoat system. Cadmium and the other fastener materials examined in this study varied widely in coating thickness on different fastener surface areas. Author
