[16E-SIS12-07] Advanced Vacuum Carburizing System for Powder Metal Parts & Components

*J. Kowalewski1 (1.Ipsen International, USA)

キーワード:Vacuum Carburizing

Powdered metal parts and components may be carburized successfully in a vacuum furnace by combining carburizing technology with the hi-tech control system. The approach differs from traditional carburizing methods because vacuum carburizing is a non-equilibrium process. It is impossible to set the carbon potential and control its composition to obtain a desired case, as in the conventional carburizing atmosphere. This paper presents test results demonstrating that the vacuum carburizing system carburized PM materials faster than traditional steel with acceptable results. In the experiments conducted, PM samples with the lowest density and open porosity showed a dramatic increase in the surface carbon content up to 2.5% C and a three times more profound case.
