| Abstract Scope |
CoCrFeMnNi alloys are valued for their excellent mechanical properties, such as high ductility at ambient temperatures and excellent fracture toughness at low temperatures. Metal additive manufacturing is noted for creating fine microstructures with superior properties due to rapid cooling rates. Despite extensive studies on the tensile properties of additively manufactured alloys, research on their wear characteristics remains limited. In this study, CoCrFeMnNi alloys manufactured by both DED and casting. Subsequently, Ball-on-flat linear wear tests were performed to determine the causes of changes in wear characteristics of cast and DED-manufactured CoCrFeMnNi alloys under different time and load conditions through analysis of worn surface, specific wear rate, and cross-sectional microstructure. |
