| Abstract: | The effects of ultrasonic on the cathodic polarization ability,cathodic current efficiency,throwing power,electrochemical reaction impedance,internal stress and hardness of nickel deposition in sulfate electrolyte were investigated.Results showed that the introduction of ultrasonic during nickel electroplating could reduce the cathodic polarization,increase the cathodic current efficiency,improve the throwing power and decrease the electrochemical reaction impedance of the nickel deposition.Moreover,the introduction of ultrasonic could also refine the grain size,decrease the internal stress and increase the hardness of nickel coating. |
| Keywords: | nickel electro-deposition sulfate ultrasonic current efficiency internal stress |
