Abstract
The plasma powder melting (PPM) method has been put into practical use for weld surface hardening. This study attempted to fabricate metal-carbide composite materials using PPM. Metal (Fe, Ni, Co alloy) and carbide (Cr3C2, NbC, WC) powders were melted by a plasma arc in graphite mold to obtain metal-carbide composite materials. In Fe-Cr3C2, Ni-Cr3C2, Fe-NbC, and Ni-NbC systems, the strength values were high in comparison with products without reinforcing. The strength is caused by change of matrix structure, dispersion of particles and residual stress between metal matrix and carbide. In all composites, bending modulus decreased monotonously with increasing carbide, and hardness increased. A 3-dimensional model of metal-carbide composites is presented.
