Description
Summary:In order to improve the problem of unsatisfactory wear and corrosion resistance of traditional materials, a composite coating of Ni-Fe-Co-P-GO is prepared on the surface of 45# steel by scanning electrodeposition technology. The morphology, composition and phase structures of the Ni-Fe-Co-P-GO composite coatings are characterized by scanning electron microscopy (SEM), energy spectrum analysis (EDS) and X-ray diffractometry (XRD). The surface hardness, wear resistance and corrosion resistance of the composite coatings are analyzed by means of a micro hardness tester, a comprehensive tester for surface properties of materials and an electrochemical workstation. The results prove formation of an amorphous Ni-Fe-Co-P-GO composite coating on the surface of 45# steel. The prepared Ni-Fe-Co-P-(GO)0.6 composite coating has maximum surface hardness with best wear and corrosion resistance due to closely connected cell structure on the surface when the concentration of graphene oxide (GO) is 0.6 g·L-1.
