The tribological properties of an EDC coating, the surface modification by the electrical discharge machining, were examined and compared with CVD coating. As a result the next things became clear. (1) Friction coefficient of an EDC coating becomes smaller as the load or velocity is larger, and its tendency is similar to that of SUS440C. (2) Each coaling of EDC, CVD is hard to wear about 5-10 times than a case without a coating when the load is under 19.6 N (10.0MPa), but the EDC coating has no wear resistance when the load is over 29.4 N (11.5MPa). (3) The EDC coating is easy to let partner materials wear, as the load or velocity is larger. From the above, it is clear that an application to the die surface and a tool is extensive.
