| 摘 要： | 通过声电沉积工艺在碳／碳复合材料表面制备了生物活性透钙磷石涂层，采用SEM、FFIR、XRD研究了超声场中电流密度对涂层组成结构和形貌的影响。发现在一定工艺条件下，随电流密度增加，涂层的平均晶粒尺寸减小，致密度增加；当电流密度小于l0mA／cm^2时涂层形貌为片状，l0mA／cm^2-26mA／cm^2时为粒状，32mA／cm^2时为花菜心状。且涂层中透钙磷石晶体的择优取向也发生变化，择优晶面依次为(021)、(111)、(220)。同时还讨论了涂层微观结构变化机理。

| Abstract: | Sonoelectrodeposition technique has been used to prepare bioactive brushite coatings on carbon/carbon composites. The effects of current density on the structures and morphology of the bioactive brushite coatings were also investigated. It is found that the coatings with plate like (021), granular like (111), and flower like(220)morphology can be fabricated by using different current densities respectively. The results show that the sizes of as deposited particles decrease with increasing current density. In addition, the mechanism of the variation of their microstructures was also discussed. |
