抄録

The effect of free carbon contents in TiC powders on some room-temperature properties of TiC-30 and -50%Ni cermet was studied. By adding sugar carbon to as-received TiC powder having a fixed carbon content of 19.60%, the free carbon content was varied from 0.03 to 1.30%. Various cermets were vacuum-sintered in temperature range of 1300° to 1400°C for 1 hr. The results obtained were as the following: (1) The density, the hardness and the strength of cermets were decreased with increase of the free carbon contents. (2) A dispersion of free carbon in cermets was microscopically observed when the TiC powder had more than about 0.5% of free carbon. (3) These results showed that the free carbon in TiC powder seemed to be inactive to possible reactions, that is, increase of the fixed carbon content of TiC or reduction of the oxidized powders under the sintering condition. (4) The free carbon content in TiC powder for cermet application was thought to be less than 0.1 to 0.2%.
