Abstract Scope |
Cemented tungsten carbide (WC-Co) plays a major role in many industrial applications including high-speed cutting turning tools and wear components. Currently, tungsten carbide material is manufactured into desired geometries using conventional powder processes. In the recent years, a promising additive manufacturing technology, Binder Jetting (BJ) process, has demonstrated success in converting WC powders into components. Unlike ductile materials, cemented tungsten carbide has more demanding quality requirements for manufacturing with Binder Jetting technology to achieve comparable properties to conventionally processed material. Engineered powder materials, flaw-less printing, and optimal sintering are all required for successful binder jetting of tungsten carbide powder materials, and become even more critical for WC with low metallic binder contents. Controlling the size and distribution of the pores within printed artifacts is crucial and determines the final part mechanical properties. In this work, the material-process-property correlations of binder jetted tungsten carbide with low cobalt content are assessed. |
