采用射频磁控溅射法在钛基体上制备了含银和钽的非晶磷酸钙（ACP）涂层。将溅射靶热压成具有和不具有8摩尔% Ta的含10摩尔% Ag的磷酸三钙烧结压坯。所制备的ACP涂层致密、光滑，各元素沿深度方向沿着分布均匀。此外，Ag作为离子存在于ACP中，与Ta的存在无关。含银ACP涂层膜在模拟体液中的再吸收性被Ta的加入抑制。在稀释的营养肉汤中检测到的银离子浓度高于Tris-HCl溶液。
Silver (Ag)- and tantalum (Ta)-containing amorphous calcium phosphate (ACP) coating films were fabricated on titanium substrates by radiofrequency magnetron sputtering for biomedical applications. The sputtering targets were hot-pressed into 10 mol% Ag-containing ß-tricalcium phosphate sintered compacts with and without 8 mol% Ta. The fabricated ACP coating films were dense and smooth, with all elements distributed homogeneously along the depth direction. In addition, Ag existed as ions in the ACP regardless of the presence of Ta. The resorbability of the Ag-containing ACP coating films in simulated body fluids was suppressed by the addition of Ta. The concentration of detected Ag ions was higher in diluted nutrient broth solution than in Tris-HCl solution.
