摘　　要：为改善骨植入体涂层材料在临床应用中存在的不足之处,如生物活性不高、抗感染能力缺乏、长期稳定性不够等,对等离子体喷涂生物活化钛涂层、抗菌羟基磷灰石涂层以及抗降解硅酸钙复合涂层等新型生物活性涂层进行了研究。所获得的涂层材料综合性能优良,有望用于新一代骨植入体。Bioactive titanium coatings,antibacterial hydroxyapatite coatings and degradation-resistance calcium silicate composite coatings have been prepared by means of plasma spraying in the light of some problems for bio-coatings existing during clinical application,which are low bioactivity,lacking of anti-bacterial effect and weak long-term stability. The obtained coatings have good comprehensive property and could be used as new bone-substitute coating materials.
