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.
