Effect of Spray Power on Characteristics of Vacuum Plasma Sprayed Hydroxyapatite Coatings

Abstract

Abstract: Hydroxyapatite coatings were made under different spray power using a Vacuum Plasma Spray System. The effects of spray power on characteristics
of hydroxyapatite coatings were investigated. In the experiment, X Ray Diffractometer and Scanning Electron Microscopy were used to detect phase compositions and
microstructures of as-received coatings. The results obtained indicated that, plasma spray power greatly effectsed the characteristics of the as-received
coatings. With the increase of spray power, hydroxyapatite content of as-received coatings decreased, showing the amorphorization of coatings was prompted. Also,
with the increase of spray power, the melt of hydroxyapatite was improved, the coatings with good microstructures were obtained.

Key words: vacuum plasma spray, hydroxyapatite, coating, XRD analysis, SEM analysis
