通过对负压铸渗理论的分析，得出了影响负压铸渗深度的因素及其影响规律（见式（９））；用碳化钨、镍包氧化铝及不同粒度氧化铝为陶瓷颗粒、耐热钢为基体进行了负压铸渗实验，得到了颗粒分布均匀的复合材料，揭示和证实了颗粒与金属液间的湿润特性及颗粒粒度对铸渗的影响规律。
By analyzing the theory of negative pressure infiltration infiltration theory, the factors that affect the depth of negative infiltration infiltration seepage and its influencing laws (see Eq. (9)) are obtained. With tungsten carbide, nickel-coated alumina and different particle size alumina as ceramic particles, The experiment of negative pressure infiltration and infiltration was carried out on steel substrate. The composite material with uniform particle distribution was obtained. The wetting characteristics between particles and metal liquid and the influence of particle size on infiltration were revealed and verified.
