摘要
在超声波作用下，对100nm左右的Al2O3粉体进行化学镀铜，从化学镀铜热力学和动力学两方面对其机理进行探讨。同时借助X射线衍射判断其成分组成，用SEM观察镀覆结果，结合EDAX光电子能谱仪对其进行表面元素分析。结果表明：引入超声波可以实现纳米Al2O3粉体的化学镀铜，以EDTA-2Na为配位剂，并加入亚铁氰化钾为稳定剂，可以有效地消除或减少复合粉体中的Cu2O，可以一次镀覆得到铜含量为5％～90％的Cu—Al2O3复合粉体。
Nano- Al2O3 composite powder electroless copper plating under the Action of ultrasonic was carried on, and its mechanism was discussed from the aspect of electroless copper thermodynamics and kinetics. Its surface element was analyzed through the plating result of SEM and using X - ray photoelectron spectroscopy （XPS）. The result indicated that it can realize Nano - Al2O3 composite powder electroless copper plating by introduced ultrasonic. To EDTA - 2Na for complexant and adding ferrous potassium cyanide as stabilizer, Cu2O among Composite Powder can be eliminated or reduced efficiently and Cu - Al2O3 composite powder of 5%90% content is obtained.
