The effects of the codeposition ions on structural and tribological properties of electro-brush plated coatings were investigated. The microstructure and phase structure were studied with scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The hardness and tribological properties of several coatings with different kind of codeposition ions were studied. Results show that among the coatings with different FeCl 2 contents in electrolyte, the Fe400 coating has the best surface property. When proper chemical ion W codeposited with iron ion is added, the hardness of the coatings is improved obviously and the Fe-W II coating has the best properties. When proper element of Cu is added, the hardness and tribological properties of the Fe-W-Cu coatings are also improved. Besides, the interface bond strength between the coating and the substrate is improved obviously, and the Fe-W-Cu II coating has the best properties.
