Abstract: The superposition of pulsed current on the electroless reaction is referred to the pulsed electroless plating. The effects of pulsed parameters (pulsed current desities and duty cycles) and temperatures on the compositions and performances of deposits and the depositing rates are investigated. The results showed that the depositing rates are accelerated by pulsed current without any great loss in the properties of the Ni-P deposit. In addition, the enhancement of the chemical reaction for electroless nickel deposition by pulsed current is found.
