Abstract
The interface shear strength of Ca-P thin films applied to Ti6Al4 V substrates have been evaluated in this study using a substrate straining method-a shear lag model. The Ca-P films were synthesized using sol-gel methods from either an inorganic or organic precursor solution. Strong interface bonding was demonstrated for both film types. The films were identified as non-stoichiometric hydroxyapatite but with different Ca/P ratios. The Ca-P films were 1-1.5 μm thick and testing and analysis using the shear lag approach revealed a shear strength of approximately 347 and 280 MPa for Inorganic and Organic Route-formed films, respectively. Overall, the exceptional mechanical properties of Ca-P/Ti6Al4 V system along with the inherent advantages of sol-gel processing support continued studies to utilize this technology for bone-interfacing implant surface modification.
