| Descripción: | The main objective of this study is to produced WC-Co-Ni ceramic-metal composites Electroless Ni coated WC-Co powders were used in powder metallurgy techniques for making samples. 2 μm - 10μm micron grain size of WC powders and 10μm grain sized Co powders obtained from Sigma Aldrich Company in this work. Co-WC powders were cold pressed under 400bar pressure before sintered 1200oC -1400oC in microwave furnace. 90% N2 + 10% H2 mixed atmosphere were used during sintering. Mechanical tests and metallographic analysis were investigated for characterization of composite materials after sintered. Experimental results carried out for 1300°C suggest that the best properties as σmax and hardness (HB) were obtained at 1300°C and the microwave furnace sintering WC and Co powders is a promising technique to produce ceramic reinforced Co composites.Keywords: Powder Metallurgy, Ceramic–Metal Composites, Microwave Powder Sintering, Scratch Tools. |
