MATERIAL-BARE 2219-F ALUMINUM ALLOY-ELEVATED TEMPERATURE-CORROSION PROTECTIVE SURFACE TREATMENT FOR-DETERMINATION OF

Abstract

Bare X-2219-F Al with Type I or Type II anodize coating applied per MIL-A-8625A exhibits no corrosion after a 4 hour heat soak at 600 F followed by 250 hours salt spray exposure. Under identical conditions the alloy with 0. 001 in. Hardas coating exhibits an average of 2.6 pits/sq. in. of exposed surface. The tensile properties of bare, Type I, Type II and Hardas anodized X- 2219-F Al prior to and following 250 hours salt spray exposure were determined and are presented.
