[Processing Technology] Vacuum Carburizing (Direct Carburizing)

Since there are no grain boundary oxidation or carburization irregularities on the surface layer, it is also possible for the inner surface of the pores! Quality improvement can be expected.

"Vacuum carburizing hardening" is a carburizing hardening method conducted in a vacuum furnace. Acetylene gas supplied into the furnace undergoes thermal decomposition, and the carbon generated penetrates and diffuses from the surface. In addition to the carburizing effect, there is no grain boundary oxidation or carburizing unevenness in the surface layer, making it possible for the inner surfaces of pores as well. Moreover, since it finishes with a bright luster, quality improvement can be expected compared to conventional carburizing hardening. 【Features】 ■ Carburizing hardening method conducted in a vacuum furnace ■ In addition to the carburizing effect, it allows for the inner surfaces of pores due to the absence of grain boundary oxidation and carburizing unevenness in the surface layer ■ Finishes with a bright luster ■ Quality improvement can be expected compared to conventional carburizing hardening ■ JIS processing symbol: HQV *For more details, please refer to the PDF materials or feel free to contact us.
