Abstract
The present study explored the potential of a novel additive manufacturing (AM) assisted investment casting (IC) process for developing indigenously hydroxyapatite (HA)/titanium dioxide (TiO2) coated magnesium AZ31B alloy for biomedical applications. The as-produced HA and HA/TiO2 indigenous coatings exhibited higher biomechanical properties (hardness and adhesion strength) as compared to un-coated samples. Further, the in-vitro corrosion and cell-culture test highlighted that the obtained coatings improved the corrosion resistance, reduced the degradation rate, and enhanced the bioactivity of AZ31B alloy. The results of the present study strongly advocated that the adopted methodology can be used for potential orthopaedic applications.
