【Abstract】 Copper-impregnated graphite throat insert material was made by the technique of impregnating copper to coarse granular graphite. The result of the study on relation between microscopic structure and the property of thermal shock resistance is that impregnating copper to coarse granular has increased the thermal conductivity and improved the general effect of toughness. And through studying on the SEM and energy level staff the relation between copper distribution and erosion property was got.更多还原
