Scarce reporting of effects of aging time and temperatures on Titania Reinforced Calcium Phosphate (T-CaP) based precursors, sols and thin film coatings inspired the authors to carry out the present investigation. Sol-gel technique was adopted and pH, density and rheological properties were comprehensively studied followed by the analysis of aging and sintering temperatures on structural and various mechanical properties of spin coated T-CaP thin films on Ti6Al4V was also carried out. 5°C aged sol was observed to be more acidic and viscous than the sol aged at 25°C. X-Ray Diffraction (XRD) revealed the multiphasic nature of coatings primarily comprised of Hydroxyapatite (HAP), Sodium Titanate, Calcium Titanate followed by traces of Rutile and Anatase phases. Maximum %weight of HAP phase (43.69%) was noted in coatings prepared from 5°C aged sol followed by sintering at 900°C respectively. Scanning Electron Microscopy revealed the smooth and crack-free coatings prepared from 25°C aged sol; whereas cracks were observed in 5 °C aged sol coatings, but crack density decreased with the increase of sintering temperature. Energy Dispersive Spectroscopy (EDX) complemented XRD results. Coatings prepared from sols aged at 5°C were rougher than one prepared from 25°C aged sol; although roughness of coatings remained <1μm. Micro-hardness examination revealed the harder nature of 5°C aged sol coatings and former increased with the rise of sintering temperature. 5℃ aged sol coatings were found to be more porous. Lower aging temperature developed more bioactive, rougher, harder and porous T-CaP coatings.
