An investigation of plasma processes in titanium(iv) isobutoxide: the formation of films on Ti and Si

The single lap shear (SLS) strengths for plasma-reacted TiiB-titanium alloy specimens bonded with a polyimide adhesive were compared with titanium substrates that had been cleaned with acetone and bonded with the same adhesive. The best SLS strength of 30.3±3.5 MPa (4390±510 psi) was obtained from samples coated with a PP TiiB film deposited at 10 W with argon as the carrier gas. Further, the failure mode for all samples pretreated with PP TiiB was interfacial at the PP film/substrate interface.
