Process of Bioceramic Coating with Laser-remelting Pretreatment

The bioceramic coating was made by Lasser remelt pretreating a layer of mixed powder CaHPO₄·2H₂OCaCO₃Y₂O₃ on the TC4 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.
