In-situ stirring and its effect on microstructure evolution and tribological performance in wide temperature induced via addition of dual-functional ceramics in laser directed energy deposition of FeCoCrNi-MoS2-SiC

Key Points

• Tribological performance improves with in-situ stirring during laser directed energy deposition.
• Key evidence shows a significant enhancement in wear resistance with the addition of dual-functional ceramics.
• Analysis of microstructure evolution in FeCoCrNi alloys highlights the role of temperature and stirring.
• Findings support the potential for improved material properties in additive manufacturing processes.
