Abstract

The space vehicle is powered by solar panels, and as a key component in the rotation mechanism of the panels, the sliding friction pair is an important power and signal transmission channel for the aircraft. In addition to ensuring high reliability in structure, conductive slip ring materials should also select electrical contact materials suitable for the space environment. In this paper, the corresponding relationship among the preparation process, properties and microstructure of AuAgCu35-5 alloy, which is used as a conductive slip ring, is studied, especially for the process link of key performance changes. AuAgCu35-5 alloy was prepared and investigated in order to obtain excellent mechanical properties by optimizing the heat treatment conditions. Studies have shown that with the increase of processing rate, the mechanical properties (tensile strength, hardness) of the material continue to improve. The relationship between tensile strength and processing rate is essentially linear. The hardness increases linearly with the increase of the machining rate at first, and then remains unchanged. Even though the processing rate continues to increase, the hardness no longer changes significantly. The AuAgCu35-5 alloy has an aging strengthening phenomenon, and the hardness increases when the temperature is kept at 400°C. The optimal heat treatment process of AuAgCu35-5 alloy is heating at 400°C for 30 minutes.
