TL;DRAbstract

Abstract : Anodized Titanium Aluminum Vanadium adhesive bonds exhibit improved corrosion resistance and a higher strength to weight ratio compared to conventional metal bonding techniques for primary and/or secondary structural applications. This work was conducted to identify chromic acid (CA) anodization and bond process conditions which produced durable, structural applications. This work was conducted to identify chromic acid (CA) anodization and bond process conditions which produced durable, structural anodized Titanium Aluminum Vanadium single lap bonds and to understand why these conditions were necessary. Heat resistant adhesives tested had reported service temperatures greater than 423K, and were: polysulfone; polyethersulfone;polyphenylquinoxaline; polyetherimide, both unfilled and 20% glass filled; and 50% calcium carbonate filled polyimide. Hydrofluoric acid (HF) added to the CA anodization solution was necessary to produce structural bonds. Chromic acid hydrogen fluoride
