Abstract Composite coatings of Ni-SiC were prepared on Ti-alloy TA15 by composite electroplating technology, while the effect of electroplating parameters on the coating structure was predicted by means of artificial neural network approach. The results showed that the increase of SiC particles in the plating bath and the stirring speed could lead to higher SiC content of the composite coating, which in turn resulted in higher coating hardness. Increase in cathodic current density caused higher coating growth rates, but too higher cathodic current density would also cause cracks in the coatings. Predictions of the coating growth rates and coating hardness were carried out via artificial neural network. After training, the neural network model was available for the prediction of the thickness and the hardness of the coating.
