摘要
采用电化学沉积在碱处理Ti6Al4V钛合金基体上生成羟基磷灰石(HA)涂层,研究了水热处理对该涂层物相的影响。结果表明,电化学沉积HA涂层结晶度低、晶粒尺寸较小,经120℃和160℃水热处理后,HA结晶度和晶粒尺寸显著增大,且随水热处理温度的增加,结晶度和晶粒尺寸增加。
The hydroxyapatite （HA） coating was prepared on the surface of alkali treated Ti6A14V alloy sheet by electrochemistry deposition, effect of hydrothermal treatment on the phase of HA coating was analyzed. The results show that the crystallinity and grain size of the HA coating are lower. However, the erystallinity and grain size of the HA coating increase significantly after 120 ℃ and 160 ℃ hydrothermal treatment, and the crystallinity and grain size of the HA coating increase with the hydrothermal treatment temperature increasing.
