Substrates surface containing with polar components has a great influence on the synthesis of sol-gel derived calcium phosphate coatings. This paper reports the synthesis of calcium phosphates coatings on native and pre-oxidated C/C-SiC (SiC-coated carbon/carbon) substrates, and compares their differences in composition, structure and in vitro bioactivity. C/C-SiC composites were prepared by CVD (chemical vapor deposition) at 1100 °C for 25 h and modified with aqua regia (HCl/HNO3) for 2 h. Then the coatings were manufactured by sol-gel combined with dip-coating technique. It is shown that the pre-oxidation promotes the formation of dispersed beta-tricalcium phosphate (β-TCP) particles, and the conversion of calcium phosphates coatings from hydroxyapatite (HA) to BCP (HA/β-TCP). The formed β-TCP is composed of hexagonal and orthorhombic systems, and HA is mainly hexagonal crystal. Additionally, the BCP coating on C/C-SiC exhibits better bioactivity compared to pure HA coating during immersion in simulated body fluid (SBF), which is result from the negatively functional groups single bondOH and single bondCOOH formed on pre-oxidated surface. These groups disturb the stability of sol via electrostatic interaction and induce the nucleation of β-TCP. Hence, the BCP coating with preferential dissolution of β-TCP phases reveals better apatite formation capability.
