Au-Co alloy deposit was prepared by selecting the best component in the bath with citrate the deposit exhibited golden appearance and high percentage of coverage. Good hardness and improving anti-corrosion capability could be achieved by adding 3~4.5%Co element and little rare-earth element to the system, and micro-hardness could increase to 180~190Hv. Optimized bath has stable performance, good throwing power and good covering power. The Scanning Electron Microscope (SEM) illustrated that the deposit was smooth, compact and crystal was nice. It is suited for electrical production; decorative coating, advance electrodeposits and hard-gold depose sit.
