Abstract：
The aim of the work was to obtain hybrid coatings containing silver, copper, and zinc nanoparticles on the TiAlV medical alloy via a sol-gel process. The developed layers were designed to bring about a bactericidal and fungicidal effect, as well as for protection against surgical scratches during the implantation of implants used in veterinary medicine. In this work, the authors focused on evaluating the microstructure (SEM + EDS); the structure (XRD, FTIR); and the surface properties, such as wettability, free surface energy, and roughness of layers with various concentrations of metallic nanoparticles (2 and 5 mol %). Our results confirmed that the sol-gel method enables the easy manufacturing of hybrid layers endowed with different porosity values as well as various shapes and sizes of metallic nanoparticles. A higher concentration of nanoparticles was observed on the surface containing 5 mol % of metallic salts. The highest degree of homogeneity was obtained for the layers containing silver nanoparticles. In addition, the silver nanoparticles were round and had the smallest dimensions, even below 20 nm. The FTIR and XRD structural studies confirmed the presence of an organosilicon matrix containing all three types of the metallic particles. We conclude that the higher concentration of nanoparticles influenced the alloy surface parameters.
摘要：
这项工作的目的是获得含银的混合涂层，铜，和锌纳米颗粒通过溶胶-凝胶工艺在TiAlV医用合金上。开发的层旨在产生杀菌和杀真菌效果，以及在植入兽医学植入物时防止手术刮伤。在这项工作中,作者专注于评估微观结构(SEM+EDS)；结构(XRD，FTIR)；以及表面特性，如润湿性，自由表面能,以及具有各种浓度的金属纳米颗粒(2和5摩尔%)的层的粗糙度。我们的结果证实，溶胶-凝胶法可以轻松制造具有不同孔隙率值以及各种形状和尺寸的金属纳米颗粒的混合层。在含有5mol%金属盐的表面上观察到更高浓度的纳米颗粒。对于含银纳米颗粒的层获得最高程度的均匀性。此外,银纳米颗粒是圆形的，尺寸最小，甚至低于20纳米。FTIR和XRD结构研究证实了包含所有三种类型的金属颗粒的有机硅基质的存在。我们得出的结论是，较高浓度的纳米颗粒会影响合金表面参数。
