摘要
在激光表面重溶预处理的ＴＣ４合金基材上预置涂敷ＣａＨＰＯ４２Ｈ２Ｏ－ＣａＣＯ３－Ｙ２Ｏ３混合粉末，再经激光熔覆处理制备了生物陶瓷复合涂层。研究了该生物陶瓷涂层的织织和性能。结果表明，采用激光表面重熔预处理作过渡层制备的生物陶瓷涂层的界面结合良好，表层为ＨＡ和β－ＴＣＰ组成的活性生物陶瓷复合涂层。
The bioceramic coating was made by Lasser remelt pretreating a layer of mixed powder CaHPO 4·2H 2O CaCO 3 Y 2O 3 on the TC 4 substrate.Effect of laser remelting preatment on microstuctures and properties was studied by SEM ESD XRD etc.The results show that laser remelting pretreatment is favorable to improvement of the mechanical properties and biocompatibility of bioceramic coating.
