| Abstract: | Nickel and silicon dioxide nanoparticle composite coatings were prepared by brush plating with direct and pulse current.The surface morphology,microstructure,hardness and wear resistance of the coatings were investigated by scanning electron microscope(SEM),transmission electron microscope(TEM),mirohardness tester and ball-on-disk tribotester.The results show that the technical parameters,pulse current,duty circle and frequency,are of great influence on the growth of crystalline and properties of the coating.Compared with the coating plated with direct current,the coatings plated with pulse currents have smaller nanocrystalline,contain more SiO2 nanoparticle and have higher hardness and wear resistance. |
