    摘要:

    本文主要以氟代羥基磷灰石(FHA)懸浮液為原料，采用懸浮液等離子噴涂技術(shù)，在鈦基體表面成功制備了FHA涂層。通過(guò)XRD，SEM，F(xiàn)T-IR以及XPS等測(cè)試手段，對(duì)不同噴涂功率制備的FHA涂層進(jìn)行表征，并測(cè)試其性能。結(jié)果表明，粉體及制備的涂層主要晶相為HA，但是粉體進(jìn)入等離子火焰形成涂層的過(guò)程中發(fā)生分解，生成α-磷酸鈣(α-TCP)，β-磷酸鈣(β-TCP)，以及磷酸四鈣(TTCP)等分解產(chǎn)物。XPS結(jié)果證明F離子成功取代了OH基團(tuán)進(jìn)入HA晶格中，導(dǎo)致FHA涂層的抗溶解性明顯提高。電化學(xué)實(shí)驗(yàn)結(jié)果表明，噴涂功率對(duì)涂層的抗腐蝕性能有較大影響。

    Abstract:

    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.
