摘要
用Ｘ射线衍射等方法，研究了从碱性镀液电沉积的锌镍合金镀层的化学组成与相结构、晶粒尺寸、显微硬度的关系．结果表明，随着合金镀层中镍含量的提高，合金镀层由η－和γ－相共存转变为只有γ－相；镀层的织构相应地由六方结构的（１００）择优面转变为立方结构的（３３０）择优面．η－和γ－相的晶粒尺寸随镀层镍含量的提高而降低；只有γ－相时，晶粒尺寸降低更为显著．镀层的显微硬度当镍含量为９．０ｗｔ．％时呈现一极小点．
Relationship between the chemical composition of Zn-Ni alloy deposited from alkaline plating solution and its phase structure, grain size and microhardness was studied by x-ray diffraction. It was found that, as the Ni content of deposits increased, the phase structure was changed from (η+γ)phases coexisted to γ-phase alone, the preferred orientation was changed from the (100) oriented face in hexagonal structure to (330) oriented face in cubic structure; and the grain size of alloy deposits decreased, especially when γ-phase is existed alone. As the Ni content in deposits increased , the microhardness of th deposits decreased first, with a minimum value at 9.0 wt. % Ni,and then increased.
