摘要
Cu-based materials reinforced by titanium carbide used in the field of brake or conducting friction were fabricated by mechanical alloying (MA) and spark plasma sintering (SPS). X-ray diffraction results indicate that the composites consist of copper matrix, Cu3Ti2, titanium carbide and graphite. Transmission electron microscope (TEM) image shows that a smooth interface exists between the titanium carbide particles and copper matrix. Moreover, the laminate structure of graphite (800 degrees C) transfers to not consistent with the laminate structure at high temperature (1000 degrees C).
