Influence of sodium saccharin on the microstructure of pulse electrodeposited Ni-CeO2 nanocomposite coating.

Author information

Department of Metallurgical and Materials Engineering, Indian Institute of Technology, Kharagpur 721302, India.


In the present study the Ni-CeO2 nanocomposite coating has been pulse electrodeposited from a watt's type bath containing 30 g/l CeO2 nanoparticles and varying amount of sodium saccharin (SS). Experimental results show that both the amount of codeposited CeO2 particle and crystallite size of Ni in the composite coating decrease with an increase in the SS concentration of the electrolyte. The microhardness increases up to 0.50 g/l SS concentration in the electrolyte; beyond it there is no further increase in the microhardness.
