Abstract The influences of pulse electroplating parameters on deposition rate, internal stress, porosity and microstructure of high speed nickel coating were studied. The results showed that the temperature, average current density, frequency, reverse pulse coefficient and duty cycle had great impact on the microstructure of coatings. Compared with the conventional method of electrodeposition of nickel, high speed pulse electrodeposition of nickel had the advantages of high efficiency, energy saving and so on.
