An Efficient Electrochemical Approach for Characterization of the Interface Strength of Nano Titania-Silica (TS) Composite Coating on Titanium Implants

Abstract

The thermal decomposition process developed in the present work is a viable technique for the formation of a nano TS (TiO2-SiO2) composite coating on Ti substrate. The electrochemical experiments revealed that the developed coatings had high degradation resistance characteristics and high biomimetic growth characteristics. There was no degradation on the coating even when it was subjected to different extent of electrochemical polarization and anodic current impression. The biomimetic growth studies of these coatings were carried out without any alkaline treatment. Surface and topographical analysis including SEM and AFM were also carried after biomimetic growth. The results of elemental analysis of the SBF solution and electrochemical characterization carried out at different stages revealed that there was efficient apatite growth even without pre-alkaline treatment.
