説明

The titanium carbide (TiC) based cermet has often been known as a material showing a higher resistance to wear than that of WC-Co cemented carbide in the use of tools for working steels. However, the brazing characteristic of cermet to tool steels is inferior to cemented carbide. Then, the studies on adhesion between the cermet and WC-Co alloy were made to get fundamental knowledges in making combination tools. The cermet and WC-Co alloy were pre-adhered at 1300°C, and finally adhered at 1360-1400°C . It was found that liquid binder of nickel appearing in cermet generally flowed out into WC-Co alloy during the course of adhesion, resulting in the hardness increase and the volume (dimension) decrease in cermet, and in the reverse phenomena in WC-Co alloy side. The flow out of liquid nickel of cermet occurred during rising temperature to adhesion temperature and lowering temperature from the above temperature. The amount of flow out of liquid nickel depended on the adhesion temperature, grain size, carbon content of specimens and cooling rate from adhesion temperature. The mechanism of flow out of liquid nickel was in detail discussed.
