Method of Ultrasonic Nanocrystal Surface Modification for Improvement of Surface Characteristics of Aisi D2 Heat-Treated With Different Tempering Conditions
Abstract:AISI D2, an alloy tool steel, has been widely used as a cold-work die steel because of its excellent wear resistance, toughness, and machinability. However, when it is used as a mold or tool under a high load, high hardness and wear resistance are required to improve its service life. This study aimed to apply ultrasonic nanocrystal surface modification (UNSM), a local surface hardening technology, to the surface of D2 steel. To maximize the surface improvement effect achievable through UNSM, it is important t… Show more
