| 摘 要： | 应用电化学共沉积技术制备HAP／聚乙酸乙烯酯杂化陶瓷膜层，XRD、XPS、SEM表征结果指出，由电化学共沉积制备的复合膜层中无机相以HAP为主，有机物含量达4％。HAP陶瓷膜层的表面结构形貌因引入有机高聚物而发生显著改变。力学拉伸实验表明HAP/聚合物陶瓷膜层与金属基体的结合力比单一HAP相有明显提高。

| Abstract: | An electrochemical co-deposition method was developed to successfully prepare the hybrid bioceramic coating of hydroxyapatite (HAP)/ Poly (vinyl acetate) on the surface of Ti alloy. The characterization of XRD, XPS and SEM showed that the composition of inorganic phase in the hybrid bioceramic coatings was mainly HAP and the content of organic phase was more than 4% (w/w). It was noted that there was remarkable change on the surface morphology of hybrid ceramic coating because of adding organic monomer vinyl acetate. The binding-pulling experiments indicated that the bonding force of the hybrid coating to metal substrate was increased as high as 2.43 MPa. |
