In the composite electrodeposition, higher nanoparticle content in nanocomposite coatings are realized by optimizing process parameters, so that these composite coatings have excellent properties. The optimized process parameters that have major influence on nanoparticle content were obtained by orthogonal test, and the result was further analyzed by BP neural network. Nanoparticle content in nanocomposite coatings was predicted and the composite coating which has the highest nanoparticle content was obtained. The surface morphology of the nanocomposite coating was surveyed and its energy spectrum was analyzed.
