Ferro-matrix friction material was obtained by in-situ carbothermal reduction from vanadium-bearing titanomagnetite in vacuum environment. The effect of RE addition (0 ~0.3 wt.%) on the microstructure and properties of ferro-matrix friction material was investigated. As a result, compared with the specimen without RE, those with RE has better connection of substrates and smaller pores size. It results the porosity decreases and, the increase of density, micro-hardness and frictional coefficient. When the adding RE is 0.1 wt.%, the connection of substrates is best, that is to say, the pores distribution is most even and pores size is minimum. Meanwhile, the highest density, hardness and frictional coefficient are obtained with 0.1 wt.% RE addition. However, there is little influence on the properties with excessive RE addition. In addition, the morphology of vanadium-titanium carbide varies with different RE addition.

Metatitanic Acid

A TiC powder is synthesized from a micron-sized mesoporous metatitanic acid-sucrose precursor (precursor M) by a carbothermal reduction process. Control specimens are also prepared using a nanosized TiO2-sucrose precursor (precursor T) with a higher cost. When synthesized at 1500°C for 2 h in flowing Ar, the characteristics of the synthesized TiC from precursor M are similar to those of the counterpart from precursor T in terms of the crystal size (58.5 versus 57.4 nm), oxygen content (0.22 wt% versus 0.25 wt%), and representative sizes of mesopores: approximately 2.5 and 19.7–25.0 nm in both specimens. The most salient differences of the two specimens are found in the TiC from precursor M demonstrating (i) a higher crystallinity based on the distinctive doublet peaks in the high-two-theta XRD regime and (ii) a lower specific surface area (79.4 versus 94.8 m2/g) with a smaller specific pore volume (0.1 versus 0.2 cm3/g) than the counterpart from precursor T.
