用磷酸锌溶液对钛表面进行水热处理，在钛表面形成磷化涂层。在250℃水热处理条件下，磷化反应在钛基材表面形成锌钛磷化涂层，低浓度的磷酸锌溶液处理14h后，涂层未被完全覆盖。而用高浓度的磷酸锌溶液处理6h后，钛表面的覆盖率完全提高。扫描电子显微镜和X射线光电子能谱分析表明，表面氧化层抑制了涂层的形成。涂层与钛基材结合紧密，涂层与钛基材的结合强度高于粘结剂的机械强度。
Phosphate coating layer was produced on titanium substrates by hydrothermal treatment with zinc phosphate solutions. Phosphatizing reaction produced zinc-titanium-phosphate coating layer on the surface by hydrothermal treatment at 250 °C. Ti substrate treated with low concentration of zinc phosphate solution for 14 h was not fully covered by the coating layer. On the other hand, surface coverage on Ti substrate treated with a high concentration of zinc phosphate solution for only 6 h was enhanced completely. SEM and XPS results indicated that the formation of the coating layer was inhibited by surface oxide layer. The coating layer was strongly attached on Ti substrate, moreover, the bonding strength between the coating layer and the Ti substrate was higher than the mechanical strength of binder.
