Researchers led by Keita Marumoto at Hiroshima University together with collaborators from Mitsubishi Materials Hardmetal Corporation, a manufacturer of cemented carbide tooling materials, investigated how laser irradiation strategies influence the microstructure and hardness of additively manufactured WC–Co cemented carbide. The results published in the International Journal of Refractory Metals and Hard Materials show that combining a laser-leading deposition strategy with a Ni-based alloy interlayer enables the fabrication of cemented carbide structures with hardness exceeding 1400 HV while suppressing tungsten carbide decomposition and porosity defects.
WC–Co cemented carbides are widely used in cutting tools and construction equipment because of their high hardness and wear resistanc
