Metal surface treatment method of die steel materials using post-deposition heat treatment

摘要

The present invention relates to a metal surface treatment method of a mold steel material using a post-deposition heat treatment, and more specifically, a laser melt lamination technique and a post-deposition heat treatment technique are performed at the same time. It relates to a metal surface treatment method of a mold steel material capable of reinforcing the surface, uniform reinforcing particles of the reinforcing layer with the mold steel powder, and exhibiting excellent hardness, abrasion and toughness.
