摘要
借助SEM(扫描电子显微镜)、盐雾试验等技术,对以不同阳极氧化工艺在镁合金AZ91D表面所得膜层的微观结构及其综合防护性能(包括耐蚀性、耐磨性及结合力)进行了比较研究,结果发现,不同工艺条件下形成的阳极氧化膜在微观结构及性能上存在显著差异,环保型阳极氧化新工艺所得膜层的综合防护性能优于经典工艺,对基体金属能提供更为有效的保护。
The microstructures of anodic films formed by different anodizing processes on magnesium alloy AZ91D and their protective performance were investigated by SEM(Scanning ELectron Microscopy) and salt spray test etc.The relevant protective performances included corrosion protection, abrasion resistance and the adhesion between anodic film and substrate. It was found that the mi-crostructure of different anodic films and their protective performance were different according to the processes remarkably. It was testified that the anodic film formed by the so called environmentally friendly new process could provide much effective protectiveness to the substrate.
