【摘要】 研究了镀液组成和工艺条件对Ｎｉ—Ｃｅ—Ｓ非晶态合金沉积层的影响，结果表明，镀层中的Ｓ含量随电流密度、镀液的ｐＨ值和硫代硫酸钠浓度的变化而变化，但与镀液中的氯化钾浓度无关；Ｘ射线衍射图说明，当镀层中的Ｓ含量超过３０％时，镀层为非晶态结构；扫描电子显微镜表明，当镀层中Ｓ含量增加时，镀层的微裂纹减少且变细，当镀层中Ｃｅ含量增加时，晶粒会细化。更多还原

【Abstract】 Effects of bath composition and deposition conditions on components of the Ni-Ce-S amorphous deposit are studied. Sulfur content in the film obtained changes with the changes of current density applied, bath PH and sodium thiosulfate concentration, but has no relation to the concentration of cerium tricbloride. X-ray diffxaction patterns show that the films with sulfur content over 30% appears in amorphous structure. SEM examination indicates that as sulfur content increases, microcracks in the film become finer and less, and as cerium content increases, the grains will be finer as well.更多还原
