摘要：
Home-synthesized FHA powders 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 composition of the coatings were characterized through XRD, SEM, FT-IR and XPS. The result shows that all coatings contain a HA major phase and the decomposition phases (α-TCP, β-TCP and TTCP). FT-IR and XPS results confirm the presence of fluorine in the as-sprayed coatings. The solubility result shows that the substitution of fluorine into the HA structure has 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 indicate that the coatings enhance the corrosion resistance of the Ti substrate. © 2020, Science Press.
