磺化石墨烯对树脂基炭刷载流磨损性能的影响
The effect of sulfonated graphene oxide on the current-carrying wear characteristics of a resin matrix carbon brush
摘要
Abstract
A novel resin matrix carbon brush ( RMCB) was prepared by dispersing sulfonated graphene oxide ( SGO) and flake graphite powder into a phenolic resin alcohol solution, followed by drying, hot rolling, pulverization, cold pressing and solidifica-tion by heat treatment. The current-carrying wear performance of the RMCB was tested by using it in a heavy-duty industrial motor at different on-load voltages from 200 to 240 V for 4 h and examining it after use. The microstructure was characterized by XRD, SEM, EDS and TEM. Results show that the flake graphite particles were bridged by SGO and the ground surface of the brush exhib-ited an interconnected carbon structure. The wear rate of the RMCB with SGO was 2. 06×10-7 mg·N-1·m-1 at 220 V, which was 31. 3% of that of the RMCB without SGO. The combined action of arc erosion wear, oxidative wear and adhesive wear was the dominant wear mechanism of the brush with and without SGO during the current-carrying wear test.关键词
