Their properties are better than those of metal-impregnated graphite sealing materials and their lifetime is increased by 4-6 times compared with the latter.

与金属浸渍石墨密封材料相比，其性能更为优良，使用寿命提高4—6倍。

The results indicate that, the fracture toughness of copper impregnated graphite is not much greater than that of graphite at room temperature, because the liquid copper does not wet the graphite.

石墨渗铜材料的断裂韧性与高强石墨相比基本相当，主要是由于铜相与石墨结合强度低而未能发挥铜相增韧的作用。

The relationship between the thermal physical and mechanics properties with the silver impregnated carbon graphite clack seat and bushing materials and thermal shock divisor was discussed.

讨论分析了浸银碳石墨阀座和衬套材料的热物理及力学性能同热震因子的关系。
