摘要
本文通过陶瓷转化处理(CCT)对 Ti6Al4V 合金表面进行了改性,无论是否有预沉积银层。在对 620 °C 下形成的陶瓷氧化层的表面形态、微观结构和相组成进行表征后,我们研究了氧化层下的表面硬度和横截面纳米硬度曲线。通过维氏压头施加离散载荷并观察压痕,检验了氧化层的静态承载能力。划痕试验用于评估氧化层的承载能力和附着力/粘合力。由于银的加入和表面形态的变化,表面的润湿性也发生了变化。往复摩擦和磨损测试用于评估摩擦学特性。在银预沉积 Ti6Al4V 样品的氧化层中发现了小而分散的银纳米颗粒和银簇,它们在降低摩擦系数和磨损体积方面具有更好的摩擦学特性。在银的帮助下,CCT 的效率显著提高。
Silver-promoted ceramic conversion treatment of Ti6Al4V alloy and its mechanical performance
In this paper, the Ti6Al4V alloy surface was modified via ceramic conversion treatment (CCT) with or without a pre-deposited silver layer. After characterizing the surface morphologies, microstructure and phase constituents of the ceramic oxide layer formed at 620 °C, we investigated the surface hardness and the cross-sectional nano-hardness profile under the oxide layer. The static load-bearing capacity of the oxide layers was examined by applying discrete loads via a Vickers indenter and observing the indentations. A scratch test was used to evaluate the load-bearing capacity and the adhesion/cohesion of the oxide layers. The wettability of the surface changed due to the incorporation of silver and the change of surface morphology. Reciprocating friction and wear test was used to assess the tribological properties. Small and dispersed silver nanoparticles and clusters were found in the oxide layer of the Ag pre-deposited Ti6Al4V samples, and they had much better tribological properties in terms of reduced coefficient of friction and wear volume. With the assistance of silver, the efficiency of the CCT was significantly improved.
期刊介绍:
The Journal of the Mechanical Behavior of Biomedical Materials is concerned with the mechanical deformation, damage and failure under applied forces, of biological material (at the tissue, cellular and molecular levels) and of biomaterials, i.e. those materials which are designed to mimic or replace biological materials.
The primary focus of the journal is the synthesis of materials science, biology, and medical and dental science. Reports of fundamental scientific investigations are welcome, as are articles concerned with the practical application of materials in medical devices. Both experimental and theoretical work is of interest; theoretical papers will normally include comparison of predictions with experimental data, though we recognize that this may not always be appropriate. The journal also publishes technical notes concerned with emerging experimental or theoretical techniques, letters to the editor and, by invitation, review articles and papers describing existing techniques for the benefit of an interdisciplinary readership.
