Abstract Cemented carbide with high hardness and high toughness properties has become a hot research area in recent years. Seven specimens of three graded cemented carbide were investigated in detail for the element content distribution and hardness by using X-ray energy dispersive spectroscopy and rockwell apparatus. Results show that all the specimens are WC-Co based cemented carbide. The addition of Co and Ni enhances the toughness， while reduces the hardness of cemented carbide. The additives TaC， TiC enhance hardness of WC-Co based cemented carbide. The enhancing effect of TaC and TiC on the hardness of cemented carbide greatly surpasses the weakening effect caused by the addition of Co and Ni.

Key words： WC-Co based cemented carbide hardness toughness Co+Ni TiC+TaC
