Uniform distribution of silver (Ag) in the hydroxyapatite (HA) coated Ti surface has been a concern for which an attempt has been made to dope Ag in HA coating with and without magnetic field. Cathodic deposition technique was employed to coat Ag incorporated hydroxyapatite coating using a sacrificial silver anode method by using NdFeB bar magnets producing 12 Tesla magnetic field. While uniform deposition of Ag was observed in the coatings under magnetic field, dense coating was evident in the coating without magnetic field conditions. Uniformly distributed Ag incorporated HA in the present study has potential to fight microorganism while providing osseoconduction properties of the composite coating.
在羟基磷灰石(HA)涂层钛表面中均匀分布银(Ag)一直是人们关注的问题,为此,人们尝试在有磁场和无磁场的情况下将 Ag 掺杂到 HA 涂层中。采用牺牲银阳极法,通过 NdFeB 条形磁铁产生 12 特斯拉磁场,利用阴极沉积技术在涂层中镀入 Ag 来制备掺入 Ag 的羟基磷灰石涂层。在磁场下观察到涂层中 Ag 均匀沉积,而在无磁场条件下涂层则明显致密。本研究中均匀分布的掺入 Ag 的 HA 具有抵抗微生物的潜力,同时为复合涂层提供了成骨传导性能。
