以钛及合金为基体、HA涂层的复合材料作为植入物应用已很普遍。HA涂层与钛及合金基体的结合强度较低,易出现界面剥落现象;ZrO2具有较好的生物相容性,而且能提高涂层和界面的结合强度,制备HA/ZrO2生物复合涂层已成为国内外学者的研究热点之一。本文综述了HA/ZrO2生物复合涂层的研究进展。
The use of HA-coated composites as an implant has been common with titanium and alloys as the matrix. HA coating and titanium and alloy matrix bonding strength is low, prone to interface spalling phenomenon; ZrO2 has good biocompatibility, and can improve the bonding strength of the coating and the interface, the preparation of HA / ZrO2 biological composite coating has been Become one of the hot spots of scholars at home and abroad. This review summarizes the research progress of HA / ZrO2 bio-composite coatings.
