- 摘要:
- 在氨基磺酸盐镀液体系中，采用电沉积法制备了纳米晶镍镀层和四种纳米晶Ni-Co合金镀层，采用FESEM、EDS和XRD表征了镀层的表面形貌、成分和晶体结构。结果表明，镍镀层和四种Ni-Co镀层的晶体结构都是简单面心立方结构；与镍镀层相比，Ni-Co合金镀层的平均晶粒尺寸减小，且当镀层钴含量为41.3%时，Ni-Co合金的平均晶粒尺寸最小为14.6 nm。在一定范围内，钴含量的增加有利于改善Ni-Co合金镀层的表面质量以及实现晶粒细化。
- Abstract:
- Nanocrystalline nickel coating and four types of nanocrystalline Ni-Co alloy coatings were prepared by electrodeposition method in the sulfamate bath system. Surface morphology, composition and crystal structure of the coatings were characterized by FESEM, EDS and XRD. The results showed that the nickel coating and four Ni-Co alloy coatings exhibited simple face centered cubic structure. The average grain sizes of Ni-Co alloy coatings were less than that of nickel coating, and the Ni-Co alloy had the minimum grain size of 14.6 nm when cobalt content was 41.3%. The increase of cobalt content could improve the surface quality and refine the grains of Ni-Co alloy coatings within a certain range.
