Wear behavior of TiC-MoSi2 composites
- 化学化工－已发表论文 
Titanium carbide (TiC) particles have been added to molybdenum disilicide (MoSi2) to form TiC-MoSi2 composites. Benefits associated with the addition of the TiC to MoSi2 include finer microstructure, higher strength, higher fracture toughness and higher hardness. Under the wear condition of this test, the wear resistance of MoSi2, increases significantly by the addition of TiC particles. The wearing rate of TiC-MoSi2 composites is as low as tenth of monolithic MoSi2. The effects of fracture toughness and hardness on wear resistance are discussed. (C) 2002 Elsevier Science B.V.
