In Part A of this study, infiltrations experiments of porous SiC samples by hexadecane with pore-size distributions comprising small and large pores were realized. Two successive stages were identified during the filling of these samples corresponding to the infiltration of the two types of pores. The experimental data were successfully treated with a new analytical function. In Part B, it was found that this function can also be applied to the analysis of the mass gain during molten silicon infiltration at 1500 °C. Prior to silicon infiltration, it was found that the operating temperature induces a shift of the pore size distributions towards larger values. A dissolution-recrystallisation mechanism can also occur during the infiltration of silicon. During the first stage, liquid silicon fills rapidly larger pores than hexadecane. The kinetics are significantly larger with liquid silicon. Consequently, the durations for the complete filling are very short with molten silicon.

在本研究的A部分中，实现了十六碳烷对多孔SiC样品的渗透实验，孔尺寸分布包含小孔和大孔。在填充这些样品的过程中，确定了两个连续的阶段，分别对应于两种类型的孔的渗透。实验数据已成功使用新的分析功能进行处理。在B部分中，发现该函数还可用于分析在1500°C的熔融硅渗透过程中的质量增加。在硅渗透之前，发现工作温度引起孔径分布向较大值的偏移。在硅的渗透过程中也可能发生溶解-重结晶机制。在第一阶段，液态硅比十六烷迅速填充更大的孔。液态硅的动力学明显更大。因此，用熔融硅完成填充的持续时间非常短。
