in high humidity. Key words: molybdenum disulfide; wear; high-resistivity brushes; humidity  ... for the brushes has rarely been found. Lubricants play a key role for the wear of brushes [8], and molybdenum disulfide is an excellent solid lubricant for brush materials, especially under extreme......
Guo-liang, DUAN Li-hui (School of Materials Engineering, Shanghai University of Engineering Science, Shanghai 201620, China) Abstract: In vacuum environment, the dense fiber-structured molybdenum-copper (Mo-Cu) composites were fabricated by infiltrating liquid copper into molybdenum fibrous preform. By controlling the relative density of molybdenum fibrous preform, the composition of Mo-Cu......
