通过双辉等离子渗金属技术在不锈钢表面进行铜铟钼三元共渗,得到了表面含有铜铟钼合金层的抗菌不锈钢。利用扫描电镜(SEM)、能谱仪(EDS)和X射线衍射仪(XRD),分析了合金层的表面形貌、组织结构,并对制备得到的不锈钢表面合金层进行了抗菌性能试验。结果表明,渗层和表面的沉积层共同构成了基体表面的合金层,渗层与基体之间存在一条扩散线,合金层表面平整光滑、均匀致密、无裂纹和孔洞。渗层中元素的含量由表及里沿梯度降低。合金层表面物相主要有:Cu、Fe、In、Cu_(3.8)Ni、MoC、Cu11In9、CuC_8、InNi、InNi_3等。渗后不锈钢对大肠杆菌和金黄色葡萄球菌具有良好的抗菌性能。
Through the dual-hull plasma infiltration metal technology in the stainless steel surface copper-indium-molybdenum ternary infiltration, the surface containing copper indium molybdenum alloy layer of antibacterial stainless steel. The surface morphology and microstructure of the alloy layer were analyzed by scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray diffractometer (XRD). The antibacterial performance of the prepared stainless steel alloy was tested. The results show that the infiltrating layer and the surface sedimentary layer together form the alloy layer on the surface of the substrate. There is a diffusion line between the infiltrating layer and the substrate. The surface of the alloy layer is smooth, uniform and compact with no cracks and holes. The content of the infiltration layer elements from the table and the gradient along the gradient down. The surface phases of the alloy layer are mainly Cu, Fe, In, Cu_ (3.8) Ni, MoC, Cu11In9, CuC_8, InNi, InNi_3 and so on. After infiltration of stainless steel on Escherichia coli and Staphylococcus aureus has good antibacterial properties.
