浸银炭石墨复合材料的密封摩擦特性
MICROSTRUCTURE OF CARBON-GRAPHITE COMPOSITES IMPREGNATED WITH SILVER AND THEIR SEALING FRICTION PROPERTIES
摘要
Abstract
Taking the extra-fine petroleum coke powder as basic constituentand adding a bit of complex oxide ceramics powder, a carbon-graphite-matrix with high strength and wearability was prepared. Its graphitization degree was controlled by selecting suitable heat-treatment technology. Densification and strengthening have been achieved using hot-isostatic impregnating with silver. The carbon-graphite composites impregnated with silver, M209G, exhibits the comprehensive advantages of carbon, graphite, ceramic and silver. X-ray diffraction, metalloscope and SEM were used to analyze the effects of the microstructure and surface morphologic of materials on friction-wear behaviour, its sealing friction specific properties was also discussed.关键词
