Abstract The effects of ultrasound agitation (100 W, 100 kHz) on the structure, morphology and properties of electrodeposited Co-Ni alloy coatings were investigated in this paper. The result shows that: when ultrasonic agitation was used during the alloy coating electrodeposition, the concentration diffusion was effectively reduced, and the electron transfer between the cathode/solution interface was also promoted. Ultrasound agitation leads to the increase of Co content in alloy coating. The Co-Ni alloy coating deposited under ultrasound agitation is more fine-grained and uniform. The ultrasound agitation can lead to the enhancement of hardness and corrosion resistance properties of Co-Ni alloy coatings.
