Research and development trends of electrodeposited multifunctional composite materials are reviewed at home and abroad, including polybasic composite electrodeposition, pulse composite electrodeposition, pulse jet electrodeposition, electrodeposition of nano-powders and functional gradient materials. Results show that wear resistance, corrosion resistance and anti-high temperature oxidation of these kinds of composite coatings are much better than those of tranditional single metal coatings, alloy coatings and their composite coatings. They will have wide application prospects in the future.
