Durability of Thermoplastic Adhesive Bonding to Metals: Ti to PEKEKK

摘要

The durability of titanium alloy (Ti-6Al-4V) bonded with thin film poly ether ketone ether ketone ketone (PEKEKK) thermoplastic polymer was investigated. Grit blasted titanium adherends modified with Sodium Hydroxide Anodization (SHA) produced durable PEKEKK-Ti tensile joints for up to 6 months of immersion soaking in Ringr's solution at 38 deg C. Two voltages (10 and 15 Volts) and times (15 and 30 minutes) were used to create different surface morphologies. Large diameter pores (approx approx 100 nm) from SHA at 15 Volts for 15 produced joints that retained 41
