The present work introduces nanostructured Zr as a possible choice of metallic implant biomaterial in competition with titanium and its new alloys. The paper reports on the preparation of anodized zirconium in a mixture of electrolytes with fluoride ions, 1 M (NH₄)2SO₄ + 0.15 M NH₄F + distilled water, at 20 V. The obtained nanostructures were investigated by SEM, EDX, XRD and AFM techniques. The SEM - EDX longitudinal and cross sectional analysis revealed the morphology of the formed oxide layers and their thicknesses, which were found to be 7.45 ± 0.18 μm. The mean nanopores’ diameter was calculated as 15.8 ± 3.3 nm. The XRD investigations enabled the evaluation of crystallite sizes and texture coefficients for zirconium and zirconium oxide containing samples. The inhibition effect against Escherichia coli and Streptococcus Aureus bacteria was evaluated and discussed as well. The AFM studies revealed that the nano-porous Zr has similar hardness parameter as the uncoated Zr, but lower surface adhesion force that could be translated into improved properties in terms of antimicrobial effects, as confirmed by its inhibition index, which makes it a very promising material for bio-medical applications.

本工作介绍了纳米结构的Zr作为与钛及其新合金竞争的金属植入物生物材料的可能选择。该论文报道了在电解质与氟离子，1 M（NH ₄）2SO ₄  + 0.15 M NH ₄的混合物中制备阳极氧化锆的方法。F +蒸馏水，20V。通过SEM，EDX，XRD和AFM技术研究获得的纳米结构。SEM-EDX纵向和横截面分析揭示了所形成的氧化物层的形态及其厚度，发现为7.45±0.18μm。平均纳米孔的直径经计算为15.8±3.3nm。XRD研究使得能够评估锆和含氧化锆样品的微晶尺寸和织构系数。对大肠埃希菌和金黄色链球菌的抑制作用还对细菌进行了评估和讨论。AFM研究表明，纳米多孔Zr的硬度参数与未涂覆的Zr相似，但是较低的表面粘附力可以转化为具有改善抗菌性能的特性，这一点已被其抑制指数所证实，这使其非常有前途生物医学应用材料。
