PRODUCTION OF COMPOSITE HARD MATERIAL

摘要: PURPOSE: To provide a method for producing composite hard material capable of obtaining an axisymmetric long-sized with simple process without need new device or special modification by using press- extruder and vacuum sintering furnace. CONSTITUTION: Plural kinds materials are optionally selected from the sintered alloys WC as grain iron-family metal main binder phase cermet TiC Ti(C,N) to produce multilayer high-humidity material. In this case, is placed into cylinder, pushed piston extruded having optional section formed. The interfaces joined diffusion in succeeding stage. A obtained way process.
