In order to research effect of plating parameters on wear resistance of Ni-SiC composite coatings, Ni coatings and Ni-SiC composite coatings were synthesized on steel substrates by electrodeposition method. The results indicate that the contents of SiC particles increase with density of pulse current and on-duty ratio of pulse current increasing. The wear resistance of Ni-SiC composite coatings predicted using ANN model has the similar shapes with the measured curve and the maximum error is about 9.6%. The wear losses decrease when current density increases from 30 to 50 A/dm^2. SiC particles in Ni-SiC composite coating are much greater in number and are dispersed homogeneously in the deposit and the coating exhibited a dense structure.
