POLYCHELATING AGENT INCORPORATION LIPOSOMES & MICELLES

Not Available Naval and Marine Corps aircraft suffer from pitting and crevice corrosion to a much higher degree than land based counterparts. Operation from air capable ships ensures that 7000 series aluminum alloys are exposed to the chloride ion from salty seawater spray and air. This aggressive corrosion environment increases: sailor maintenance demands, inspection requirements, and ultimately, total costs per flight hour. A logical solution to the corrosion problems on aircraft surfaces would result from application of a thin fluoropolymer wallpaper system with embedded revolutionary corrosion inhibiting features. One of the present drawbacks of applique technology is the inability to prevent the chloride ion from reaching the substrate where the applique is gouged, torn away, or along seams and edges. This research seeks to address these problems by incorporating an inhibitor that retards pitting, corrosion fatigue and stress corrosion cracking of aluminum alloys, into the applique or adhesive system. The goal of this proposal is to utilize the Fluorogrip method for surface modification of fluoropolymers and incorporate corrosion inhibitors directly into the film or pressure sensitive adhesive. The adhesive system to be used for this project will be tailored for near complete removal without solvents in cases where film replacement is required.
