| Abstract Scope |
Cemented tungsten carbides are the most widely used materials in metal-cutting industry and wear resistant applications, due to the excellent combination of hardness and wear resistance. Compared to beam-based additive manufacturing, binder jetting can produce carbides with acceptable microstructure and properties. Previous work has demonstrated that cemented carbides with high metallic binder can be printed and sintered to full density with uniform microstructure. It is more challenging to fabricate materials with commercial quality when the metallic binder is below 15 wt.%, due to a reduced liquid content during sintering. This work will compare cemented tungsten carbides with 17 wt.%, 13 wt.%, and 10 wt.% of metallic binders made using binder jetting. The interactions among powder, printing, and sintering to develop microstructure and properties comparable to conventionally processed carbides will be discussed. In addition, applications enabled by using DFAM principles will be presented. |
