本文针对高温、高压旋转接头的关键构件伺服环的工况条件，研制了耐磨减摩性能优良的纳米结构的铜合金材料。制备的纳米结构铜合金伺服环的抗拉强度（a。）为930MPa；显微硬度（HV）为280；摩擦系数（K）为0．2。
Servo ring is a key component of high temperature and high pressure rotary joints. The wear property of servo ring determines the whole performance of rotary joint system. In this study, nanostructured copper alloys with high wear resistance property were proposed and synthesized for application in servo ring. The tensile strength of the nanostructured copper alloys is as high as 930 MPa. The microhardness and friction coefficient are 280 HV and 0.2, respectively.
