Antifriction and noise reduction processing method for ceramic artificial hip joint surface

The invention discloses an antifriction and noise reduction treatment method for a ceramic artificial hip joint surface, which is characterized in that an ultra-smooth surface is arranged on a main frictional wear area of a ceramic artificial hip joint ball head, and the ultra-smooth surface can reduce a friction coefficient between frictional contact interfaces to achieve an antifriction effect. Besides, the micro-texture array is arranged on the ultra-smooth surface, the micro-groove texture of the friction area can store tissue fluid and abrasion particles, lubrication is provided, meanwhile, three-body abrasion is avoided, continuous contact of a friction interface is broken through the micro-groove texture, friction vibration and noise can be restrained easily, and the friction performance of the friction surface is improved. And the service life and the comfort of the artificial joint are improved. 本发明公开了一种陶瓷人工髋关节表面的减摩降噪处理方法，在陶瓷人工髋关节球头的主要摩擦磨损区域上设有超光滑表面，超光滑表面能够减小摩擦接触界面间的摩擦系数，起到减摩作用。此外，在超光滑表面上设有微织构阵列，摩擦区的
