| Abstract: |
| In order to know the brush-plating characteristic of Ni-( nano) SiC system, the sedimentation process of brush-plating solution system containing: Ni solution, ( nano) SiC and dispersant was studied. Test results show that when the concentration of dispersant is above 2.50/o , it can fully disperse the SiC particles, and in the process, it is not likely to form large congregating grains, so the final deposit density is large, at the same time the volume of precipitated dust particles are small; in the same condition, when temperature goes up, it causes the continuous relative viscosity goes down and fasten the pervasion and deposition speed; when the content of ( nano) SiC in brush-plating solution is less than 3g/L, the SiC distribution tends to be stable with the effect of dispersant, and the deposit speed slows down. |
