Characterization of Plasma Sprayed Hydroxyapatite Coating

Abstract

Abstract: In the experiment, hydroxyapatite coatings were obtained by using vacuum plasma spraying system. XRD and SEM were used to estimate the as
received coating. The results indicated that, both amorphorization and thermal decomposition of hydroxyapatite took place in the process
of plasma spraying. Amorphous phase was formed due to rapid cooling of the melted hydroxyapatite droplet. The thermal instability of hydroxyapatite
at temperature 1300～1400℃ caused a decomposition of HA powder into CaO and TCP. A rough-surfaced coating was obtained by plasma spraying. Pores and
microcracks were observed as the characteristics of as received coating. A sintering process between the splats occurred in the process, which
was caused by the degradation of thermal exchange property between coating and titanium substrate.

Key words: plasma spray, hydroxyapatite, coating, microstructure
