<p>Metallic implants have been widely used for their structural rigidity, mechanical strength, and long lifespan as a replacement for load-bearing bones. However, the primary concern with metal-based implants is stress-shielding and implant-tissue interface caused by large variations in mechanical properties of the used implant material and tissue interface, affecting the performance of actual body functions by deteriorating surrounding natural bones and tissues. The present work attempts to characterize microwave sintered Ti-µ-HAp bio-composite with various compositions having enhanced stress-shielding effect and interface properties through their tribological characteristics using nano-mechanical, surface-wear, wettability, and corrosion tests. In vitro bio-compatibility tests with mouse fibroblast cells have been performed to analyze cell adhesion and growth. Detailed microscopy and elemental distribution characterizations have been studied to exhibit the diffusion of HAp in the composite. An appreciable reduction in modulus, nano-hardness, and coefficient of friction with increasing HAp composition exhibits desired tailored properties for load-bearing implant applications. A comprehensive study confirms enhanced bioactivity (− 50% increased cell absorbance for 3&#xa0;wt.% HAp composite compared to commercially Pure Ti), considerable corrosion rate with apatite formation, and tribological properties for the proposed metal–ceramic-composites, which could be a better substitute for metallic biomaterials for hard tissue applications.</p> Graphical Abstract <p></p>
