摘要
尝试利用自制的空化场电化学装置,在水溶液中制备纳米镍磷合金粉体材料,实验装置中包括以电火花技术为基础的空泡发生系统,反应容器,循环冷却系统,真空抽滤系统等。实验结果表明:在空化场的作用下,成功地在NiSO4和NaH2PO2反应溶液中制备出纳米尺度的镍磷合金粉体材料,该材料具有非晶态结构。材料的颗粒尺寸随空化场能量的提高而减小。典型的纳米镍合金的颗粒尺寸为80nm。
Nanoscale NiP alloy powder in the solution was produced by means of a homemade electrochemistry system with acvitative field The electrochemistry system consists of a cavitative generating apparatus based on electric spark technique, reaction container, circulating cooling device and a filter by vacuum The experimental results indicate that the nanoscale NiP alloy powder with the microstructure of amorphous have been obtained in NiSO4 and NaH2PO2 solution upon cavitative field The powder size of the Ni alloy decreases with increasing energy of cavitative field The typical powder size of the sample is about 80 nm
