Abstract
This study aimed to investigate the wear performance of laser direct energy deposited Fe-8Cr3V-2Mo-2W alloy under various wear environments, in terms of different heat treatment conditions. Ball on disk tribology tests were performed using high-carbon steel and zirconia balls as counter materials. The wear rates of the alloy depended significantly..... More

Korean J. Met. Mater. 2018;56(6):430-439. Published online 2018 Jun 4
DOI: https://doi.org/10.3365/KJMM.2018.56.6.430

Abstract
AISI M4 and CPM15V are used as tool steels since they have high hardness and wear resistance. This study is concerned with die and mold hardfacing using laser melting deposition with M4 and CPM15V powders. For this purpose, the two types of metal powders were deposited on SKD11 base metal,..... More
