Wear Resistance, Die Life, Hardness, Hardenability, Coating, Tool SteelsAbstract
The aim of this study, indicate of optimum die life application for using some coating methods of forging die against to wear also as use different die steel and different coating materials. And another aim is decrease in the die costs which occurs wear of the die. Hot forging efficiency in direct proportion to wear of the die. At dies, workpiece is flowing on the die surface during forging processes, at a result of this causes friction between workpiece and surface of the die. At all of cycle, thermal loads and flow friction occur and this situation causes softening of the die as to be thermal. Therefore, surface hardness of the die will decrease. Losing of surface hardness and which occurs friction between die and work piece will negative effect life of the die. As to be die material, three different die steel will be used (DIN 1.2344 (ORVAR® 2 MICRODIZED) and DIN 1.2344 (UNIMAX®) At this time, different coating will be applied. These are FEXOY® and ABP+DIETOX®. As a result of coated operation, will follow cycle time proper die material will be selected.
