通过浸涂到溶胶-凝胶中，在钛基底上生长羟基磷灰石和氟羟基磷灰石的生物相容层。为了提高磷灰石基涂层的附着力，先用钛酸钙覆盖基材。因此，制备并分析了羟基磷灰石、氟羟基磷灰石和CaTiO3涂层。使用X射线光电子能谱（XPS）研究了涂层（CaTiO3、CaTiO3 + 羟基磷灰石和CaTiO3 + 氟羟基磷灰石）的化学成分。定量XPS分析数据显示了CaTiO3、羟基磷灰石和氟羟基磷灰石薄膜在生长后和体外处理后的不同特征（洁净度、均匀性等）。 (C) 1999 Elsevier Science B.V. 保留所有权利。
Biocompatible layers of hydroxyapatite and fluorhydroxyapatite were grown on Ti substrates by means of dip-coating into sol-gel. In order to improve the adhesion of apatite-based coatings, the substrates were a priori covered with calcium titanate. Therefore, the hydroxyapatite, fluorhydroxyapatite and CaTiO3 coatings were produced and analysed. The chemical composition of the coatings (CaTiO3, CaTiO3 + hydroxyapatite, and CaTiO3 + fluorhydroxyapatite) was studied by using X-ray photoelectron spectroscopy (XPS). The data of quantitative XPS analysis displayed the different features (cleanness, homogeneity, etc.) of CaTiO3, hydroxyapatite, and fluorhydroxyapatite films after the growth and after the treatment in vitro.
