Hardness and Fracture Toughness of a Cemented Carbide
In this paper the hardness and fracture toughness values for nanostructured cemented carbides were tested and analyzed. The experimental part included the testing of three samples: WC with 5% cobalt (WC-5Co), WC with 10% cobalt (WC-10Co) and WC with 15% cobalt (WC- 15Co). Hardness was tested by Vickers method (HV30) according to HR EN ISO 6507-1: 2005, and fracture toughness was determined by the Palmqvist method according to ISO 28079: 2009. Palmqvist's method uses the length of cracks that propagate from the tip of the Vickers pyramid imprint to determine fracture toughness. The results show that by increasing the amount of cobalt in cemented carbides hardness values drop, and the fracture toughness increases. They also indicate that using nanostructured cemented carbides increases hardness with a slight change in toughness.
