| Abstract: | The electroplating liquid of sulfamate nickel was made and the best liquid composition and technological parameters were found.The coating was analyzed with scanning electron microscope,ultra depth of field microscope,GALVANOTEST,XRD diffractometre,microhardness tester.It is shown that the best liquid composition included sulfamate nickel 360 g/L,NiCl2 20 g/L,H3BO4 38 g/L.The electroplating temperature was between 45 and 60℃,the current density between 5 and 18 A/dm^2.The largest current density of nickel/SiC compound electroplating was 15 A/dm^2.The electroplating speed and the coating hardness were 113μm/h and 638 HV respectively when current density was 15 A/dm^2. |
