The invention discloses a zirconia ceramic hip joint with ultrahigh surface smoothness and a preparation method thereof.The zirconia ceramic hip joint comprises an artificial limb body, the artificial limb body comprises a hip white prosthesis, a femoral head body and a femoral stem body, the femoral head body is installed at the bottom end of the hip white prosthesis in a clamped mode, and the bottom end of the femoral head body is fixedly connected with the top end of the femoral stem body; according to the method, stripping and cutting effects are formed on the surface of the zirconium oxide ceramic hip joint through a plasma treatment technology, and high energy of an ion beam can cut small particles and an oxide layer on the surface, so that the surface is smoother and purer; and then, an aluminum titanium oxide and lithium coating is sprayed on the surface of the treated zirconium oxide ceramic hip joint, so that the zirconium oxide ceramic hip joint with ultrahigh surface smoothness is obtained, the surface of the ceramic hip joint is smooth, the frictional wear of the zirconium oxide hip joint is reduced, and the service life of the zirconium oxide hip joint is prolonged.
本发明公开了一种超高表面光洁度的氧化锆陶瓷髋关节及其制备方法，包括假肢本体，假肢本体包括髋白假体、股骨头本体和股骨柄本体，髋白假体的底端卡合安装有股骨头本体，股骨头本体的底端与股骨柄本体的顶端固定连接，髋白假体与股骨头本体之间安装有密封衬垫，本发明先通过等离子处理技术，对氧化锆陶瓷髋关节表面形成剥离和切割作用，离子束的高能量可以切割表面微小颗粒和氧化层，从而使表面更加平滑和纯净，然后对处理后的氧化锆陶瓷髋关节表面喷涂氧化铝钛及锂涂层，从而得到一种超高表面光洁度的氧化锆陶瓷髋关节，陶瓷髋关节表面光滑，减小了氧化锆髋关节的摩擦磨损，延长氧化锆髋关节的使用寿命。
