The electroless deposition of nickel on alumina substrate was investigated with respect to the deposition behavior. The weight gain of the alumina substrate indicated that a three-stage mechanism exists for the deposition process, namely incubation, nucleation plus growth, and growth. The exclusive growth stage starts around 5 min after reaction. The activation energies as well as the effect of the deposition parameters on the rate of the nucleation and growth stages were investigated. The growth stage has a greater activation energy than the nucleation stage.
