对于医用材料的表面改性,在于改善材料的耐蚀性、耐磨性和硬组织相容性。对于牙科植入物材料,则须赋予以硬组织相容性、软组织相容性、抗菌性和耐蚀性,而且对不同部位所用材料的要求有所不同,故须进行不同的改性处理。表面改性方法按所采取的改性介质之不同,可分为水溶液中改性 For the surface modification of medical materials, is to improve the material corrosion resistance, wear resistance and hard tissue compatibility. For dental implants, the material should be hard tissue compatible, soft tissue compatible, antibacterial and corrosion resistant, with different requirements for the material used in the different parts. Therefore, different modification treatments are required. Surface modification methods according to the different modified media taken, can be divided into aqueous solution modified
