| Abstract: | Ni-based coatings dispersed with nano Si3N4 powder were made on copper matrix by using supersonic dispersion technology. The effects of supersonic wave on stirring, electrolyte temperature, contents of nano particles, hardness and microstructure of the composite coating were studied. The microstructure of the surface coating was examined under a scanning electron microscope, and wear resistance of the coating was tested on an MM-200 wear tester. The results show that the composite coating with good properties can be obtained by using supersonic dispersion technology. |
