Abstract:
The grinding of steel tools to the final shape generates sludge containing metallic swarf considered undesirable for direct recycling. After cleaning and separation of this steel swarf, its morphology often leaves it inappropriate for standard powder metallurgical uses. However, the possibility exists of utilizing field assisted sintering techniques to densify this swarf directly into new parts, thereby avoiding the need for remelting. This technique also allows for the generation of new metal matrix composites through its quick sintering time. The application of field assisted sintering as a recycling tool is realized through the densification of two different steels, PM T15 and D2, exploring the influence of varied parameter sets and tool setups on their sintering. For proof of concept, a cutting disc made of D2 swarf has been produced, which will be tested in the near future.
