中文摘要:
      本文主要以氟代羟基磷灰石(FHA)悬浮液为原料,采用悬浮液等离子喷涂技术,在钛基体表面成功制备了FHA涂层。通过XRD,SEM,FT-IR以及XPS等测试手段,对不同喷涂功率制备的FHA涂层进行表征,并测试其性能。结果表明,粉体及制备的涂层主要晶相为HA,但是粉体进入等离子火焰形成涂层的过程中发生分解,生成α-磷酸钙(α-TCP),β-磷酸钙(β-TCP),以及磷酸四钙(TTCP)等分解产物。XPS结果证明F离子成功取代了OH基团进入HA晶格中,导致FHA涂层的抗溶解性明显提高。电化学实验结果表明,喷涂功率对涂层的抗腐蚀性能有较大影响。

英文摘要:
      Home-synthesized FHA powder were used to obtain a water-based suspension. And the FHA coating was fabricated on a Ti substrate by suspension plasma spraying technique. The effect of spraying power on the microstructure and properties of coatings was studied. The crystalline phases and chemical compositions of the coatings were characterized through XRD. The result showed that all coatings contained a HA major phase and the decomposition phases (α-TCP, β-TCP and TTCP). FT-IR and XPS confirmed the presence of fluorine in the as-sprayed coatings. The solubility result showed that the substitution of fluorine into the HA structure had a positive effect on the dissolution resistance of the HA. The corrosion behavior was studied in a SBF solution using potentiodynamic polarization test, and the results indicated that the coatings enhanced the corrosion resistance of the Ti substrate.
