Type HP D - directly heated

7.-8649-UOS-HP-D-250-C.960x0-aspect.jpg

Description

In this sintering process, the tool or component is heated in a direct current passage, alowing cycle times of a few minutes are possible. The use of direct current pulses results in an additional increase in sintering activity for many materials due to the processes that take place at the contact points of the powder particles (Joule heating, plasma formation, electromigration, etc.), so that significantly lower temperatures and/or pressures are required than for conventional hot pressing or sintering.

Nanomaterials can be sintered without significant grain growth

  • FGM ("Functionally Graded Materials")
  • Composite materials
  • Innovative hard metals
  • Aluminum and copper alloys and intermetallic compounds
  • Structural and functional ceramics
