| Abstract Scope |
High entropy alloys (HEAs) are alloys that contain five or more principal elements in approximately equal atomic percentages. These alloys, whether in the form of bulk materials or coatings, exhibit potential for harsh environment applications due to their exceptional combination of mechanical, thermal, and corrosion-resistance properties. This research aimed to develop Fe-rich CrMnFeCoNi HEA coatings using wire arc additive manufacturing (WAAM). Microstructural analysis, mechanical testing, and tribological evaluations were conducted to assess coating properties. The wear behavior of these coatings against a WC-Co countersphere was tested at room temperature. Various characterization techniques, including X-ray diffraction (XRD), electron backscatter diffraction (EBSD), and Raman spectroscopy for phase analysis, scanning electron microscopy (SEM) for cross-section microscopy and phase compositions, were employed. SEM was used to reveal surface morphologies and cross-sectional analysis of the wear track. Friction and wear behavior of additively manufactured parts were discussed in relation to their mechanical properties and microstructure. |
