Microstructure and Wear Properties of TiC-Al Composite Fabricated by Field Activated and Low-Pressure Assisted Combustion Synthesis
A novel method termed field activated and low pressure assisted combustion synthesis (FALPCS) was developed for an in situ fabrication of TiC-Al composite from Ti, C and Al elemental powders. With the Al content of 30 wt% and application of a pressure as low as 2 MPa, a highly dense sample was successfully obtained on a versatile Gleeble thermal simulation instrument. The TiC particles are fine in the order of ~0.5 µm, with a uniform dispersion in aluminum. The study on un-lubricated sliding wear of the synthesized material revealed a wear mechanism that combines the characteristics of both adhesive and three-body abrasions.
