Calculating Vacuum Metal Infiltration Rate and Depth of BN-Al Composite Materials

For the first time, the metal infiltration depth and infiltration rate of the BN-Al composite prepared by metal infiltration have been calculated and studied. The calculation results show that the infiltration depth gradually increases with the increase of time, and the final infiltration depth can reach 0.21 m. As time increases and voids decrease, the infiltration rate gradually decreases. The maximum impregnation rate is 0.65cm·min-1. This calculation and research provide a positive idea for the calculation and prediction of metal infiltration in void media in the future study.
