Effect of surfactant on the ceria

The nickelceria (NiCeO2) nanocomposite coatings have been pulse electrodeposited from a Wattstype
electrolyte containing nano-sized CeO2 particles produced by high-energy ball mil领 technique
(HEBM). Sodium Lauryl Sulphate (SLS) has been added in the electrolyte as a cationic surfactant. The
effects of the surfactant on the zeta potential, co-deposition and distribution of ceria particles in the
nickel matrix and hardness of composite coatings have been investigated. Experimental results show
that the addition of SLS up to 0.10 g/l increases the amount of co-deposited ceria particles in the nickel
matrix and microhardness of the nanocomposite. However, when the amount of SLS in the electrolyte is
more than 0.1 g/l, there is a tendency to form agglomerates of ceria particles in the nickel matrix resulting
no further increase in hardness of the NiCeO2 nanocomposite coatings. 纳米粒度及Zeta电位分析仪
