介绍在奥氏体型不锈钢基材上预置涂覆具有一定梯度的生物陶瓷粉末(HAP或CSHPO42H2O+CaCO3)的激光熔覆.经SEM,EDS,XRD分析表明,低输出功率、高扫描速率是获得激光生物陶瓷涂层的主要控制因素.预置涂覆CaCO3与CaH(PO4)2H2O混合粉末涂层,在大于常规方法合成HAP所需比例下,可激光合成含Ca5(PO4)3(OH)等生物活性陶瓷的复合涂层,且存在一定量非晶态的自由表面区.
Since 70s some scholars have tried to coat bioceramic on metal substrate by Plasma sPray, CVD and PVD etc. which is considered as one of most hopeful procedure combining bioceramie with metal.However,lin these processes the bioceramic coating has not goo
