摘要

对铝合金 6063 进行了两种不同的表面处理：硫酸阳极氧化（SA）和铈转化涂层（CeCC）沉积，以评估新表面的抗菌性能。通过扫描电子显微镜、能量色散光谱仪（SEM/EDS）和 X 射线光发射光谱（XPS）对阳极氧化样品和铈转化涂层的微观结构和成分进行了表征。对所有新表面的粗糙度和润湿性进行了测量。使用铜绿假单胞菌进行了细菌附着性研究，阳极氧化样品的结果令人满意。

Tailoring AA6063 for improving antibacterial properties

Aluminium alloy 6063 was subjected to two different surface treatments: anodizing in sulphuric acid (SA) and the deposition of cerium conversion coatings (CeCC), in order to evaluate the antibacterial properties of the new surfaces. The microstructure and composition of the anodized samples and the cerium conversion coatings were characterized by scanning electron microscopy, energy dispersive spectrometry (SEM/EDS) and X-ray Photoemission Spectroscopy (XPS). Roughness and wettability were measured for all new surfaces. Bacterial adherence studies were carried out using Pseudomonas aeruginosa, with promising results for the anodized samples.
