| Abstract Scope |
Hot-work mold steel is usefully applied in industries such as extrusion molds and die-casting molds. These molds are undergoing research to improve surface durability, wear characteristics to improve their lifespan. Nitriding is generally applied as a surface heat treatment method to improve the lifespan of molds due to the high strength of aluminum. In this study, gas-controlled nitriding of AISI H13 steel was performed at 520 °C for 10 hours according to the nitriding potential (Kn) condition. The the nitrided layer was confirmed by analyzing the image and measuring the cross-sectional micro vickers hardness of the nitrided H13 steel specimen. In addition, in order to confirm the wear characteristics in the temperature region (about ５０0℃) generated in the aluminum manufacturing process, a high-temperature wear test was conducted to confirm the high-temperature wear characteristics according to the nitriding potential. |
