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.
