Abstract
- Hydroxyapatite (HA) coatings were treated with saturated steam at various temperatures and holding periods. The results show that during plasma spraying a large amount of HA decomposes or transforms to amorphous calcium phosphate (ACP), which results in low crystalline HA coatings. After treated with saturated steam the crystallinity of the HA coatings increases significantly. The relative index of crystallinity indicates that the process temperature together with the corresponding steam pressure has a more pronounced effect on HA crystallinity than the holding period. In addition, HA nanocrystallites form as a result of this process.
