【摘要】 研究了在TiH2粉末表面包覆金属Ni的化学镀液中各种化学成分、温度、pH值等因素对包覆粉末增重的影响,确定了最佳的配方及操作条件。该方法不需要对TiH2粉末进行敏化和活化等预处理,具有操作简单、镀液稳定性好等优点。Ni/TiH2包覆粉末释氢过程被显著地延迟,这种延迟效应对泡沫铝制备具有重要的实用价值,采用Ni/TiH2包覆粉末作为发泡剂成功地制备出多孔泡沫铝材料。更多还原

【Abstract】 Ni-coated TiH2 foaming reagent were prepared by the electroless plating method with each factor in the fluid such as chemical composition, temperature, pH value and so on. The best formula and the operating condition were determined. The rates of nickel deposit were easily controlled through suitable stabilizing agent and complex agent introduced in the bath. This method has the advantage of the operation simply and the fluid stability. The releasing hydrogen temperature of Ni/ TiH2 power is notable delayed, and the delaying effect can be used in the production of Al foams. The high-quality Al foams were prepared successfully using Ni/TiH2 powers as the foaming reagent.更多还原
