Synthesis and characterization on atomphospheric plasma sprayed amorphous silica doped hydrxoyapatite coatings

► We synthesize silica-HA coatings by air plasma spraying and analyze their microstructures and mechanical properties. ► This paper discusses the importance of pre-substrate heat treatment on the mechanical properties of silica-HA coatings. ► The biomechanical properties of the silica-HA coatings are competitive as compared to HA coatings.
