Abstract

image

Performing a surface densification prior to case hardening enables to adjust a definite carbon depth profile in powder metallurgical components. Due to the mechanical surface treatment, the open porous microstructure is transferred into a densified graded porous near surface layer, avoiding capillary effects of open pores.
