摘要
Hard gold has excellent physical and chemical properties, and is widely used in jewelry and the electronics industry. The deposition of hard gold has long been focused on cyanide-based aqueous electrolytes, which are highly toxic with relatively low electroplating efficiency due to the coreduction of hydrogen. Ionic liquids have recently been studied as a solvent for the electrodeposition of various metals. Herein, choline chloride-urea ionic liquid was used as the solvent with 5,5-dimethylhydantoin as the complexing agent and Co2+ was added to produce cobalt-hardened gold deposits. The addition of Co2+ promoted grain size refinement and improved the hardness of deposits. With 62.5 mg/L Co2+ present in the electrolyte, the coating showed a high degree of hardness (2.3 GPa) and relatively good corrosion resistance.
