利用微弧电泳/水热复合方法,在形貌复杂的骨螺钉表面制备涂层.该方法首先利用电解抛光对骨螺钉表面进行表面预处理,采用微弧电泳技术在其表面制备羟基磷灰石涂层,再利用水热合成对微弧电泳涂层进行封孔.利用XRD、SEM、AFM等分析手段对涂层显微结构进行分析,利用体外浸泡实验和电化学实验对涂层耐腐蚀性能及其对钙磷盐的诱导特性进行了评价.结果 在电解抛光电流0.14A、抛光时间2min的工艺条件下进行电解抛光预处理,可以提高基体和涂层的结合性能.由于骨螺钉的特殊形状,在微弧电泳电解液中添加丙三醇,并通过调整电解液中丙三醇含量优化微弧电泳工艺(电压155 V,反应时间20 min),能有效抑制尖端放电现象,防止膜层组织疏松和大量的氧化物堆积,以及涂层剥落甚至基体烧蚀的现象.再优化水热合成工艺参数(处理液pH值8.5,反应时间1.5h,反应温度393 K)对微弧电泳涂层进行封孔,得到微弧电泳/水热复合涂层.结论 微弧电泳/水热复合涂层表面形貌为菜花状结构,由纳米棒状羟基磷灰石组装而成,均匀致密,结晶性好.电化学腐蚀测试表明,制备复合涂层后,骨螺钉的腐蚀电流密度降低了一个数量级.在模拟体液中浸泡6天,骨螺钉的形貌依然完整,说明水热复合涂层在改善<span style=\"color:red\">生物</span>相容性的同时,提高了骨螺钉的耐腐蚀性能.但微动摩擦磨损测试显示,水热复合封孔处理后磨损性能下降.","authors":[{"authorName":"朱世杰","id":"9dac8c53-fe08-4685-b737-a2abb6650642","originalAuthorName":"朱世杰"},{"authorName":"王剑锋","id":"3fb338d8-fc07-477d-8214-53240d9ce96f","originalAuthorName":"王剑锋"},{"authorName":"刘欣玉","id":"79b7cadb-5a5a-43c3-ba33-b41d389795fc","originalAuthorName":"刘欣玉"},{"authorName":"王利国","id":"6427a7aa-c152-49cc-b1dc-dad4bf4957a3","originalAuthorName":"王利国"},{"authorName":"任晨星","id":"fb36db54-28fb-417c-b94e-254f166d8a8d","originalAuthorName":"任晨星"},{"authorName":"常蕾","id":"52c167f7-ee64-403c-8fa0-96ac515d545f","originalAuthorName":"常蕾"},{"authorName":"王俊","id":"99341704-40d8-4f0d-b6b8-5f52acb77c88","originalAuthorName":"王俊"},{"authorName":"关绍康","id":"9f23efe3-f592-4b12-8b3c-2e07815b6ce0","originalAuthorName":"关绍康"}],"doi":"10.16490/j.cnki.issn.1001-3660.2017.03.003","fpage":"20","id":"2b7d0407-1e62-4005-a6eb-6dcf1120a675","issue":"3","journal":{"abbrevTitle":"BMJS","coverImgSrc":"journal/img/cover/BMJS.jpg","id":"3","issnPpub":"1001-3660","publisherId":"BMJS","title":"表面技术
