| 摘 要： | 从锌合金层的微观形貌、组成、厚度、耐蚀性等以及化学镀Ni-P层的微观形貌、成分、相结构、孔隙率、耐蚀性、结合力等方面研究了浸锌层对化学镀Ni-P ?层的影响.结果表明，浸锌层对铝硅合金压铸件基体与化学镀层的结合起重要作用，浸锌层厚度薄且致密、均匀；后续的化学镀Ni ?合金层也细致均匀，结合力好，耐蚀性强. |
| 关 键 词： | 浸锌 化学镀Ni-P合金 形貌 结合力 耐蚀性 |

| Abstract: | This paper describes the effect of pre-zinking processes on the quality of electroless nickel(EN) plating on a silicon-containing Al-alloy,by analyzing micromorophology,composition,thickness and corrosion resistance of zincate deposit,and the micromorphology,component,phase constituent,porosity,corrosion resistance and adhesion of EN plating as well.The results showed that zinking deposit was an important bridge connecting Si-containing aluminum alloy and EN plating.It was concluded that if there came to be a thin,well-distributed zinc on Si-contained aluminum alloy,the sequent EN deposit would be thin with good adhesion and high anti-corrosion performance. |
| Keywords: | zinc immersion electroless nickel(EN) morphology adhesion corrosive resistance |
