TIC-PARTICLE-REINFORCED FE-BASED COMPOSITE MATERIAL AND METHOD FOR PREPARING SAME

摘要

The objective of the present invention is to provide a method for enhancing the oxidation resistance of a TiC-particle-reinforced Fe-based composite material. According to an aspect of the present invention, provided is a method for preparing a TiC-particle-reinforced Fe-based composite material. The preparation method comprises the steps of: preparing a TiC preform; and impregnating a liquid Fe alloy into the TiC preform, and then solidifying same. According to one embodiment of the present invention, the TiC preform may be a TiC sintered body fabricated by sintering powder in which a Ti oxide layer is formed on at least a portion of the surface thereof.
