Abstract

Electric brushes for aerospace vehicles—conductive rings electrically contact sliding friction pairs, are important power and signal transmission channels for aerospace vehicles. They are key stand-alone products that affect the life and reliability of satellites. In addition to ensuring high reliability in structure, friction pair materials should also select electrical contact materials suitable for space environment. This paper studies the corresponding relationship among the process, performance and organization of AuNi9 brush wire as one of the sliding friction pairs, especially for the process link of key performance changes. AuNi9 alloy was prepared and investigated in order to obtain excellent mechanical properties by optimizing the heat treatment conditions in this paper. The results show that the microstructures of the alloy are mainly composed of α-Au solid solution and A small amount of Au-Ni phase. The strength and hardness of the material continue to increase with the increase of deformation rate, and the strength is basically linear. However, the hardness has a limit value, and even if the deformation rate continues to increase, the hardness does not change significantly. The AuNi9 alloy has obvious aging strengthening phenomenon. When the temperature is kept at 300°C, the hardness increases with the heat treatment. The optimal heat treatment process of AuNi9 alloy is heating at 300°C for 30 minutes.
