초록

본 연구에서는 용융가압함침 공정을 이용하여 TiC, $TiB_2$, $Al_2O_3$ 세라믹 입자가 분산된 SUS431 금속복합재료를 제조하고 미세조직을 분석하여 세라믹 입자에 따른 제조성에 대해 검토하였다. 젖음성이 나쁜 $Al_2O_3$의 경우 내부에 결함이 다수 존재함을 알 수 있었으며, $TiB_2$ 및 TiC 입자 강화 복합재의 경우 상대적으로 결함이 적고 강화재가 균일 분산되었음을 확인하였다. 특히, TiC-SUS431 복합재료의 경우 TiC와 Fe계 기지합금의 우수한 젖음성 및 용융가압함침공정 적용으로 우수한 계면 특성을 가지며 결함이 적고 균일한 미세조직을 가지는 것을 확인하였다.

Various ceramic particulate such as TiC, $TiB_2$, $Al_2O_3$ reinforced SUS431 matrix composites were successfully fabricated by a novel liquid pressing infiltration process. Microstructures of the SUS431 composite were analyzed to determine manufacturability of composites. $Al_2O_3$-SUS431 composite had lots of defects due to poor wettability between the $Al_2O_3$ and steel matrix. On the other hand, TiC was uniformly dispersed in the SUS431 matrix than $TiB_2$ and $Al_2O_3$ due to good wettability and interfacial properties.
