【Abstract】 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. The measuring results for intensity. thermal-conductivity. expansion properties of carbon-graphite-matrix at different thermal treatment temperatures and after silver impregnated were described. and at time some kinds of the antithermal shock divisor of carbon-graphite materials impregnated with silver were estimated.更多还原
