Preparation of TiC Hard Metal by Presssureless Infiltration Method

Abstract:

The steel matrix composites pressureless infiltration technology was studied in this paper. It is necessary to develop a reasonable process, select the appropriate gel system and additives, and prepare the complex shape of the large-size steel matrix composites by using gel-casting. For reactive melt infiltration technique, the porous skeleton was prepared by gelcasting preparation of the titanium powder and ceramic particles mixed, and the C-containing liquid metal infiltration of the porous skeleton. To improve the wettability between the molten metal and the ceramic phase, it is used for the process Ti-C in situ reaction to accelerate the impregnation process. Finally, the steel matrix composites with higher density were prepared.
