| 中文摘要: |
| 为改善B4C与其它金属的结合性能，采用化学镀法在B4C粉体上镀Ag制备包覆型陶瓷颗粒。通过粗化、敏化、活化表面镀前处理，用硝酸银镀液成功地得到在B4C上均匀镀Ag的包覆粉体，利用SEM观察到包覆程度可达95%，通过详细讨论镀液的配方、助剂、镀液与B4C粉体的配比对包覆效果的影响，最终得到硝酸银用量控制在8- 12g/L能得到所控制的沉积反应速度；包覆反应过程中助剂控制在聚乙二醇8 - lOg/L、乙醇3-5mUL较为合适。 |
| 英文摘要: |
| 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. |
