    Generally, press molds have thermal and mechanical impact wear during usage. To improve the life of the mold, enhancement of mechanical properties such as abrasion resistance and shockproof capability is required. To solve this, we propose the multi-layered cladding process of functional materials with different mixing ratios. AISI-D2 material, known as cold die steel, was used as base material and AISI-M4 and -H13 powders were used for surface cladding on the base metal for high resistance wear and shockproof capability. Four cases of specimens were prepared to compare mechanical properties after tests. Through this study, a specimen multiple cladded with mixing M4 and H13 powders for middle layer and M4 powder only for top layer showed 80% improvement in shockproof capability. We posit that this method based on multi-layer cladding with a combination of functional metal powders increased mold life.
