The Influence of Production Conditions on Some Physical Properties of Tungsten Carbide and of a Complex Carbide Based on It
The microhardness and abrasive power of tungsten carbide and of a complex TiC-WC carbide have been determined for various conditions of reduction and carbidization. It was found that both increase with rise in the reduction and carbidization temperatures. This increase in microhardness and abrasive power of high-temperature WC can be attributed to the greater mobility of the tungsten and carbon atoms, which leads to healing of the macro- and microdefects in the grains during reduction and carbidization, particularly in the case of WC produced at temperatures close to the recrystallization temperatures.
