Development of Cold Sprayed Titanium/Baghdadite Composite Coating for Bio-implant Applications

Titanium/Baghdadite composite coatings have been deposited on SS316L using cold spray technology to explore their potential use as bio-implant coatings. Microstructural and mechanical characterization have been conducted to evaluate the quality of the coatings. The electrochemical corrosion behavior of the developed coatings has been evaluated in a simulated body fluid environment. The results show that baghdadite content influenced the corrosion resistance of coatings; more the baghdadite content, better is the corrosion resistance. In general, the developed coatings were successful in enhancing the corrosion resistance of SS316L. Also, the developed coatings outperformed earlier reported cold sprayed titanium/hydroxyapatite composite coatings.
