Biocompatibility study of nanocomposite titanium boron nitride (TiBN) thin films for orthopedic implant applications

Thin films of Titanium Boron Nitride (TiBN) were sputtered onto SS 316 L substrates and were characterized for their microstructure and biocompatibility. The X-ray diffraction (XRD) showed reflections of TiN and an absence of boron containing phases. High resolution transmission electron microscopy (HRTEM) mapping, ion scattering spectroscopy (ISS), and X-ray photoelectron spectroscopy (XPS) determined the presence of boron. The mechanical...
