| Abstract Scope |
Metal additive manufacturing has transformed fabrication processes, enabling the production of intricate shapes not achievable through traditional casting. Additive manufacturing's rapid cooling and high thermal gradients result in fine microstructures with exceptional mechanical properties, making it well-suited for various alloys. The CoCrFeMnNi high entropy alloy has garnered attention due to its remarkable ductility at room temperature and fracture toughness at cryogenic temperatures. However, limited research has simultaneously analyzed wear properties considering variations in time, velocity, and load parameters for HEA manufactured using Directed Energy Deposition. This study involved fabricating HEA powder through gas atomization under an Ar atmosphere with a gas pressure of 1.5MPa and orifice diameter of 5 pi. The fabricated powder was processed using the DED method, followed by ball-on-disk testing under different conditions to investigate wear properties. Through analyzing friction coefficients, wear rates, and microstructure, this research aims to comprehend the factors influencing wear behavior. |
