| Abstract: | The mixed powders CaHPO4.2H2O-CaCO3 were prepared on the sudece of TC4 that was pretreated by difFerent bonding layer. And the effect of Y2O3 powder on the bioceramic coating was discussed. With this process, the bioceramic coating were successly composed and cladded by laser only once. The mechanical properties of the coating is good, and the E mate between the coating materials and the body bone was improved. Adding Y2O3 in coating is favorable to composing HA phase and to improvement of the properties of the coating layer. |
