| Abstract Scope |
Tribo-corrosion degradation accelerates material degradation in a multitude of environments beyond the single effect of wear or corrosion. In a bid to extend the service life of structural conventional alloys, multi-principal element alloy (MPEA) developed with additive manufacturing (AM) offers a plethora of possibilities in current and emerging structural applications. With the possibility to suppress elemental and phase segregation coupled with microstructural refinement achieved with AM, reduced wear rate, enhanced regenerative passivation, noble corrosion potential and ultimately better tribo-corrosion resistance of current MPEAs are viable potentials. This presentation will compare the tribo-corrosion response of single-phase FCC CoCrFeMnNi HEA LENS additively manufactured, and vacuum-arc melted, in 3.5 wt.% NaCl solution at room temperature. Highlight of this study promotes the potential of utilizing additive manufacturing of MPEA for use in extreme environments that require a combination of tribo-corrosion resistance, mechanical durability, extended service life and net shaping with low dimensional tolerance. |
