摘要
以硝酸铜、氢氧化钠、氨水为原料,利用预先制备出的纳米氧化铜为模板,在水热条件下制备出了分散均匀、晶相纯净的微纳米铜粉末,研究了反应时间对产物形貌的影响,分别用XRD、SEM及摩擦磨损实验机表征制备样品的物相、形貌及摩擦学性能,结果表明制备出的微纳米铜粉末具有良好的抗磨性能.
Uniform cupper micro-nanopowders were synthesized by the hydrothermal method with cupric nitrate trihydrate,ascorbic acid,sodium hydrate and ammonia water as raw materials.The influence of the reaction time on the morphology was discussed.Structures,morphology and friction performance of the as-synthesized samples were characterized by X-ray diffraction（XRD）,SEM and friction testing machine.The results showed that the cupper powders have good wear-resistance performance.
