采用超声辅助阳极氧化法对碳纤维增强碳（C/C）复合材料进行了磷酸氧化处理。目的是在表面处理的C/C复合材料和随后沉积的磷酸钙（CaP）涂层之间产生化学键。在0.5M磷酸水溶液中，以50 mA/cm 2的电流密度对C/C进行超声辅助阳极氧化处理后，其表面能明显提高。在处理后的C/C基体上发现了大量的含氧基团和一些含磷基团。含氧基团的形成可能是由超声波和电场的能量输入促进的。含磷物种可以通过CPO或COP键合与C/C键合。在形成的物种中，超声促进了（H2 PO 4）−在C/C上的形成。以USAT-C/C-50为基体，采用超声辅助电化学沉积法（USECD）制备CaP涂层时，USAT-C/C-50表面具有较强的CaP诱导能力，在初始沉积过程中有大量CaP沉积在其表面。USECD后，在USAT-C/C-50上形成了非常强结合的CaP涂层。涂层的平均剪切结合强度为（12.14±1.30）MPa，是未处理C/C涂层的（6.78±1.06）MPa的2倍。
The current work describes the ultrasound-assisted anodic oxidation treatment of carbon fiber-reinforced carbon (C/C) composites with H3PO4. The aim was to create chemical bonds between the surface-treated C/C composites and subsequently deposited calcium phosphate (CaP) coatings. The surface energy of C/C obviously increased after undergoing ultrasound-assisted anodic oxidation treatment at a current density of 50mA/cm2in aqueous 0.5M H3PO4solution (USAT–C/C-50). A large number of O-containing groups and some P-containing groups were found on the treated C/C substrate. The formation of O-containing groups may have been promoted by the energy input of the ultrasound and electric field. P-containing species could be bonded to C/C by CPO or COP bonding. Among the species formed, the formation of (H2PO4)−on C/C was promoted by ultrasound. When USAT–C/C-50 was used as the substrate for CaP coatings deposited by ultrasound-assisted electrochemical deposition (USECD), the surface of USAT–C/C-50 acquired strong CaP induction ability, and large amounts of CaP were deposited on it during the initial deposition process. After USECD, very strong-bonding CaP coatings formed on USAT–C/C-50. The average shear bond strength of the coatings obtained on the USAT–C/C-50 substrate [(12.14±1.30)MPa] was about twice that of the coatings obtained on untreated C/C [(6.78±1.06)MPa].
