| 摘 要： | 以碘酸钾、三氯乙酸、甘氨酸和甲酸为添加剂，加入到标准镀铬液中，测定了镀液的分散能力、光亮电流密度范围、深镀能力、阴极电流效率。结果表明：甲酸使阴极电流效率和深镀能力较高；甘氨酸使分散能力较高。二者均能扩大光亮电流密度范围。三氟乙酸、碘酸钾能显著提高阴极电流效率，但镀层粗糙发暗。

| Abstract: | Potassium iodate, trichloroacetic acid, glycine and formic acid were added respectively to the standard chromium plating bath as an additive. Throwing power, covering power, bright deposit current density range and cathodic current efficience of the bath were measured. The results show that glycine and formic acid both can extend the bright deposit current density range with higher throwing power for the former and higher cathodic current efficience for the latter. Potassium iodate and trichloroacetic acid can both increase cathodic current efficiency markedly but the chromium deposits are dark and rough. |
