Abstract
ABSTRACT Adhesively bonded titanium alloy joints were prepared through flame-based surface treatment, and their failure behavior and substrate surface properties were investigated. The commercially available ITRO surface treatment technique was applied to Ti-6Al-4 V alloy substrates to modify their surfaces prior to bonding with an epoxy film adhesive. Adhesively bonded single-lap joint specimens were tested under static tensile loading to determine their strength and failure mode. Scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy were employed to observe the morphology and chemistry of the treated titanium alloy surfaces. ITRO treatment significantly increased the strength of the joint specimens. The strength enhancement was probably due to the interactions of the silicon oxide film that was formed on the surface of the titanium alloy substrate with both the adhesive and the substrate.
