| 摘 要： | 为了提高AZ91D镁合金磷化-阴极电泳层的耐蚀性能,采用分散的纳米SiO2改性阴极电泳漆。结果表明:改性后的漆膜表面有较均匀的小突起,有利于提高其与基体的附着力、漆膜的硬度及抗冲击性能;改性后的漆膜耐蚀性明显优于未改性漆膜。

| Abstract: | Dispersed nanometer SiO 2 particulates were used to modify phosphating-cathodic electrophoretic coating on AZ91D Mg alloy so as to improve the corrosion resistance.The adhesion,hardness,anti-impact performance and corrosion resistance of the modified composite coating were evaluated.It was found that there were tiny uniform protrusions on the surface of the nanosilica-modified electrophoretic coating,which was beneficial to the improvement of adhesion,hardness and anti-impact ability of the coating.As a result,nanosilica-modified electrophoretic coating had much better corrosion resistance than the unmodified counterpart. |
