Abstract: In the process of electroless plating used to Ni coated ZrO2 ultrafine powders, the relationship between Ni2+ concentration in solution
and time at different temperatures was determined. The effect of Ni2+ concentration, NaF and surfactants on the speed of Ni deposit was obtained.
Apparent activity energy was concluded. The goal that even mixing Ni with ZrO2 was attained. Experimental results show that
Ni is coated on ZrO2 powder surface and the speed of Ni deposit can be raised and apparent activity energy can be dropped by NaF and surfactants.

Key words: Ni coated ZrO2, electroless plating, activity energy, NaF, surfactants
