采用微弧氧化法于(CH3COO)2Ca-CaC3H5(OH)2PO4溶液中制备了富含Ca、P成分的钛合金微弧氧化陶瓷层,研究了陶瓷层中的相结构、Ca和P的分布、电压与电流密度对Ca和P在膜层中分布的影响。结果表明,陶瓷层主要由金红石型和锐钛矿型TiO2及非... 采用微弧氧化法于(CH3COO)2Ca-CaC3H5(OH)2PO4溶液中制备了富含Ca、P成分的钛合金微弧氧化陶瓷层,研究了陶瓷层中的相结构、Ca和P的分布、电压与电流密度对Ca和P在膜层中分布的影响。结果表明,陶瓷层主要由金红石型和锐钛矿型TiO2及非晶相组成;沿膜层由表及里,Ca在膜层的含量分布呈现类似二次曲线递减趋势,P在膜层中的含量则大体均匀,但在膜基交界面迅速降为零。随着电压或电流密度的升高,膜层中Ca、P相对含量增大,Ca的增长速度远快于P,使得Ca、P的摩尔比随电压的升高而增大。 展开更多

Objective: To explore chemical component changes of dog bone at different lengthening time and in different bone regions of interest, and to evaluate the mineralization during Ilizarov lengthening process. Methods: The ash weight, the concentrations of calcium, phosphorus and the calcium/phosphorus ratio were measured at different intervals (2, 4, 6, 8, 12 weeks) since lengthening and the lengthened part was compared with a control area at each interval. Results: The ash weight, the concentrations of calcium and phosphorus in the lengthened area differed at all development time. The calcium/phosphorus (Ca/P) ratio in the lengthened region remained significantly lower than that in the control region up to 12 weeks after the lengthening. Conclusions: These results suggest that also other inorganic ions play an important role in the mineralization process and that they become relatively more important since 8 weeks after the lengthening. 展开更多
