| Abstract Scope |
In this study, metal composites were prepared using TiC as the reinforcing material and FC250 as the matrix material through the Liquid Pressing Infiltration process. Heat treatment was conducted to enhance the mechanical properties, and the wear test was performed using the ball-on-disc method to assess the wear behavior of the composite. The test temperatures were room temperature (RT), 50°C, and 100°C, respectively. The hardness of FC250 was 153 HV. After incorporating TiC into the FC250, the hardness increased approximately two-fold in all heat treatments. Among the heat treatment conditions, the quenching-tempering condition showed a wear width approximately 5 times wider and a wear depth about 1.4 times deeper at all wear test temperatures. The microstructure of the base material was transformed into acicular martensite through heat treatment, which increased its hardness and enhanced wear resistance. |
