| Abstract Scope |
In this work, laser powder bed fusion (LPBF) is used for the additive manufacturing of composite samples consisting of tungsten carbide particles with a nickel binder. Such process can become a viable low-energy alternative to the conventional production of ceramic-metal composites for applications including tooling, electronics, and wear components. Single track experiments are used to evaluate the melting behavior of the composite material. Samples are then printed with of process parameters that adequately melted the material. The density, microstructure, and functional properties of these samples are measured. Highly dense (>98%) samples are successfully manufactured and analyzed as a function of LPBF parameters. Macro- and microdefects resulting from the laser processing are also discussed. A methodical approach to evaluate an acceptable processing region is presented and used to investigate the feasibility of additively manufacturing tungsten carbide-nickel composites via LPBF. |
