MATERIAL - L-NICKEL FASTENERS, ELECTROPLATED, GALVANIC CORROSION EFFECTS ON BARE X-2219-T6 ALUMINUM ALLOY -EVALUATION OF

Abstract

Assemblies of sulfuric acid anodized X2219-T6 aluminum with tin-zinc alloy plated L-nickel rivets will not pass 250 hour salt spray tests after exposure to either 430 or 515 F. Similar assemblies having brush coatings of Alodine 400 in rivet holes and plated rivets inserted with wet D.C. XP-214 primer will pass 250 hours salt spray tests after a heat soak at 430 F. The assemblies (with the above treatments) show minor galvanic corrosion after 250 hour salt spray tests following heat soak at 515 F, but are considered satisfactory for use.
