The Effect of Cell Behavior on Plasma Sprayed HA Coatings with Different Post Treatment
The initial interactions of plasma-sprayed HA coating surface with osteoblasts was investigated. Two kind of post-treatment methods were been used for HA coating: (1) Heated in air at 650oC for 30 min, (2) Heated in water vapor at 125oC, 0.15Mpa for 6 hours. The third passage rabbit osteoblasts were cultured on the HA coating plates for 24 h. The results showed: The lower dissolution rate and more surface hydroxyl groups (OH-1) group in the HA coating resulted in greater numbers of adhered osteoblasts and higher cell activity, The post-water vapor treated HA coating have better biological behavior in vitro.
