Abstract Scope Cold spray processing is a solid state deposition process commonly used to deposit dense metal coatings. The technique has potential, however, to be used to develop surface coatings for biomedical applications. Next generation surface coatings for titanium implants must exhibit both rapid osseointegration behavior and good mechanical stability to ensure a prolonged implant lifespan. We report on the relationship between processing, microstructure characterization, and biological performance of functionally graded biocomposite cold spray coatings. Coatings with varying composition of hydroxyapatite and titanium (20% HA, 50% HA, 80% HA, and functionally graded) were fabricated using high-pressure cold spray deposition. As-processed coatings were characterized using optical microscopy, scanning electron microscopy, x-ray diffraction, and contact angle goniometry. Adhesion strength of the coatings was measured using a tensile pull-off adhesion test. Biological performance of the as-deposited coatings was characterized via in vitro cell culture using mouse osteoblasts. Osteoblast viability, differentiation, and mineral deposition were investigated.
