| Abstract: |
| Hydroxyapatite is one of the most hopeful biomedical materials. Hydroxyapatite ( HA) coatings on the Ti6A14V and HA/Ti02 composite substrates were obtained by electrophoretic deposition process. Zeta potential was used to determine the content of triethanolamine and HA particles in the stable butyl alcohol suspension. HA deposit yields increased with deposition temperature and deposition voltage and showed a linear relationship with depositon time. The relationships between the deposit yield and the parameters of electrophoretic deposition process were disscussed theoretically. SEM results indicate that the HA coatings on HA/Ti02 composite substrates prepared by two step electrophoretic deposition processes are even dense and uniform. |
