Abstract

As it is widely stated in the literature, biofilms are responsible for most chronic infections, which have grown exponentially over the past three decades. The use of so-called alloys, as a new generation of materials, enables us to find the golden mean in the arena widely known as implantology. The use of the surface layer, using the chosen Atomic Layer Deposition method, is to be the basis for minimizing the risk of an organism reactions. Therefore, the primary objective of this study was to observe the impact of physicochemical properties of the surface layers (bactericidal) on the processes that occur on the implants surface made of titanium biomaterials used in bone structures. The study also attempted to evaluate the physicochemical properties of the ZnO coatings, deposited on the substrate of one of the new generation Ti13Nb13Zr alloys, using the ALD method. Included in the assessment of the physicochemical properties of the surface layers formed in this manner, we perform pitting corrosion resistance tests, scratch tests, tribological tests and surface wettability tests. Based on the obtained data, the differing physicochemical properties of the alloy with ZnO coatings are found to be dependent on the applied surface modification. For the conducted tests, differences are determined for the tests on the corrosion resistance, surface wettability and the abrasion resistance for samples with and without the ZnO coating. In addition, tests show that the coating applied to the alloy, which is previously subjected to the sand-blasted process, is characterized by improved adhesion.

用于骨骼植入物的表面改性 Ti13Nb13Zr 合金的物理化学特性研究。
正如文献中广泛指出的那样,生物膜是大多数慢性感染的罪魁祸首,而在过去的三十年中,慢性感染呈指数级增长。作为新一代材料,所谓合金的使用使我们能够在众所周知的种植领域找到黄金分割点。使用所选择的原子层沉积法进行表层处理,是将生物反应风险降至最低的基础。因此,本研究的主要目的是观察表面层的物理化学特性(杀菌)对骨结构中使用的钛生物材料植入物表面发生的过程的影响。该研究还试图评估使用 ALD 方法沉积在新一代 Ti13Nb13Zr 合金基底上的氧化锌涂层的物理化学特性。在评估以这种方法形成的表面层的物理化学特性时,我们进行了抗点蚀测试、划痕测试、摩擦学测试和表面润湿性测试。根据获得的数据,发现带有氧化锌涂层的合金的不同物理化学特性取决于所应用的表面改性。在所进行的测试中,有氧化锌涂层和没有氧化锌涂层的样品在耐腐蚀性、表面润湿性和耐磨性测试中存在差异。此外,测试表明,涂覆在之前经过喷砂处理的合金上的涂层具有更好的附着力。
