Radiofrequency magnetron sputtering deposition at low temperature (150 degrees C) was used to deposit bioactive glass coatings onto titanium substrates. Three different working atmospheres were used: Ar 100%, Ar + 7%O(2), and Ar + 20%O(2). The preliminary adhesion tests (pull-out) produced excellent adhesion values (approximately 75 MPa) for the as-deposited bio-glass films. Bioactivity tests in simulated body fluid were carried out for 30 days. SEM-EDS, XRD and FTIR measurements were performed. The tests clearly showed strong bioactive features for all the prepared films. The best biomineralization capability, expressed by the thickest chemically grown carbonated hydroxyapatite layer, was obtained for the bio-glass coating sputtered in a reactive atmosphere with 7% O(2).
低温（150°C）下的射频磁控溅射沉积被用于将生物活性玻璃涂层沉积到钛基体上。使用了三种不同的工作氛围：100%Ar、7%O(2)混合 Ar 以及 20%O(2)混合 Ar。初步的附着力测试（拔出）表明，所沉积的生物玻璃薄膜具有极好的附着力（约 75MPa）。在模拟体液中进行了 30 天的生物活性测试。进行了 SEM-EDS、XRD 和 FTIR 测量。这些测试清楚地表明，所有制备的薄膜都具有很强的生物活性特征。在含有 7%O(2)的反应性气氛中溅射的生物玻璃涂层具有最佳的生物矿化能力，表现为化学生长的碳酸羟基磷灰石层最厚。
