| Abstract: |
| In order to modify the bonding property of B4C with metal, the coated ceramic powder is prepared using chemical plating to coat B4C powder Ag. Through roughing, sensitizing and activation, and with AgN03 plating reagent , B4C powder covered rate can get t0 95% . The effect of formulation of plating solution , assistant reagent and proportion of B4C and plating solution on coating is discussed in detail. The proportion of AgN03 is controlled at 8 ~ 12g/L which is benefit to the velocity of reaction. It is suitable to reaction when assistant reagent PEG is selected as 8 ~lOg/L and EOH is selected as 3 ~5mL/L. |
