Microstructure and Wear Resistance of Cu-TiC Composites Fabricated by Mechanical Alloying and Spark Plasma Sintering
The microstructure and wear behavior of Cu-TiC composite which prepared by spark plasma sintering (SPS) and mechanical alloying (MA) were discussed in this paper. X-ray diffraction patterns and scanning electronic microscopy (SEM) images indicate that TiC were formed during sintering process. The pin-on-disc wear test was carried. Confocal scanning laser microscope (CFSLM) images indicate that mechanical mixed layer appeared on the worn surface the mechanical mixed layer broken up when normal load reached 200N. The composites displayed excellent wear resistance with 2.38×10−5 mm3/Nm specific wear loss.
