Abstract :

Tungsten carbide is known to have excellent high hardness and wear resistance carbide ceramics feature. Thanks to its superior properties and wear resistance carbide cutting-plotter teams, if desired, the industry has a wide application area. In this study, the WC-based material, ceramic material Co. To produce composite samples. In other words, ceramic and metal powders, with powder metallurgy technique, of mechanical properties and composite materials to produce the survey covers. WC powders (80%) 2 μm and 10 μm grain size grain size of ceramic-based material with a metal-based 2 μm Co(20%) composites were produced. Mixture of powders of various composition, the composition of which will be weighed and mixed in 24-hour cap in the mechanical stirrers in a homogeneous way. Samples (approximately 5 grams) in the form of capsules, pressed in a cylindrical mold. 15 mm in diameter and 2-5 mm high, made of extruded samples. 90N% + 10H2% gas atmosphere in the sintering process (1200-1300-1400)oC sintered between temperatures. Experimental studies were examined in accordance with literature data obtained by analyzing the results.In addition, the production of composite materials obtained by this method has provided a new perspective. The results obtained with this study, produced by microwave sintering technique WC-Co greatly improved the quality of composite materials.
