摘　　要：研究用脉冲辉光放电沉积炉制备碳/碳复合材料的工艺。结果表明,与普通工艺相比该法大大降低了工艺气体消耗,而且具有较高的渗入效率。文中给出了对于碳/碳复合材料的显微组织、密度、弯曲强度的研究结果。通过分析计算沉积气体在电场下的分解与电离等,提出了等离子体沉积机理的模型。The preparing process of carbon/carbon composites in a pulse glow discharge depositing furnace has been investigated in this paper. The experiment results show that this process is superior to the ordinary processes in that it has less consumption of gas and high infiltration efficiency the results of the investigations on the microstructure, density ,bending strength of carbon/carbon compositcs were given in this paper.A model of plasma infiltration mechanism was proposed through serious analyses and calculations of the decomposition and ionization of infiltration gas in the electric field.
