碳/碳复合材料具有优良的机械性能,是矫形外科和齿科领域一种很有潜力的医用生物材料.为了使它具有生物活性,本文通过一种施加超声波的新电沉积方法,声电沉积法,在其表面制备了磷酸钙生物活性陶瓷涂层.我们的实验结果表明,通过该工艺可获得致密、结合力改善的磷酸钙生物活性涂层,而且该工艺无需精确控制阴极表面产生的氢气.此外,本工艺还为具有优越力学性质的生物相容性导电材料表面制备生物活性磷酸钙涂层提供了一种新的选择.
Carbon/carbon composites are considered to be one of the most promising biomedical materials for orthopedic and dental surgery because of their excellent mechanical properties. In order to make them bioactive, calcium phosphate coating was applied on the surface of C/C by a novel process of electrodeposition with adding to ultrasonic wave, named sonoelectrodeposition. It was shown that homogenous, densified and improved adhesive coating was obtained in different carbon materials and the H2 bubbles evolving from C/C cathode needn't be precisely controlled. In addition, this process could provide a new choice for depositing bioactive calcium phosphate coating on the biocompatible conductive substrate with excellent mechanical properties.
