| 摘 要： | 通过电沉积方法制备光亮镍-铁舍金镀层,利用扫描电镜测定镀层表面显微形貌(SEM),X射线衍射仪测定合金饺层的相结构(XRD),然后对合金镀层进行浸泡腐蚀实验,观察其腐蚀行为,并测定其庸蚀速率.结果表明:镍-铁合金镀层在质量分数为3.5%的NaCl溶液中的腐蚀速率较在质量分数为5%的H2SO4溶液中的腐蚀速率小,即:在质量分数为3.5%的NaCl溶液中有较好的耐蚀性,最小的腐蚀速率为0.21 mg/(dm2·h),且在电流密度为4～6 A/dm2工艺条件下获得的舍金镀层在两种溶液中都具有较好的耐蚀性能. |

| Abstract: | Bright Ni-Fe alloy coating was prepared using electrodeposited method.The microstructures of the alloy coating was determined by scanning electron microscope(SEM);the phase compositions of the alloy coating was analyzed by X-ray diffraction(XRD);and immersion corrosion testing was then done on the alloy coating to observe the corrosion behavior and corrosion rate.The results show that the corrosion rate of alloy coating in 3.5% NaCl solution is slower than in 5% H_2SO_4 solution,and the better corrosion res... |
