Abstract

Possibility to form compositionally graded layer on the tool steel surface by EDM using Cr and WC-Co electrodes was investigated in this study in order to discuss the applicability of inexpensive carbon tool steel as metal mold material. Experimental results showed that a compositionally graded CrC-WC containing layer can be formed by EDM finishing on the chromium carbide containing layer using WC-Co electrode, and the surface roughness was less than 1 µm, which indicates high applicability of the surface as a final metal mold surface. It was also found that the tungsten in the compositionally graded layer exists in some states such as amorphous and some crystal structures of tungsten carbide. The surface hardness can be further improved by the compositionally graded layer containing tungsten carbide.
