    摘要:

    在室溫下的仿生溶液(FCS)中實現(xiàn)了鈦合金表面的仿生礦化．得到羥基磷灰石(HA)涂層。跟蹤分析了礦化過程中溶液pH值的變化，比較了礦化溶液中可能形成的各種磷酸鈣陶瓷的過飽和度，發(fā)現(xiàn)HA的過飽和度最大，從而證明FCS溶渡為HA涂層的形成提供了較好的熱力學條件。

    Abstract:

    A hydroxylapatite (HA) coating was produced by means of bionic mineralizing in a fast calcific solution(FCS)at room temperature. The pH changes of FCS during the deposition process were measured. The supersaturations of various calcium phosphates formed during FCS were compared, during which that of HA was found to be the greatest. Optimnal thermodynamic conditions were important for the formation of HA coatings in the bionic mineralizing process.
