Mechanical and metallurgical behavior of ER4043-AlN composite by wire arc additive manufactured

Lightweight components paid a lot of attention to Wire Arc Additive Manufacturing (WAAM) because of its ability to create engineering components at low cost and with little material waste. By using metal inert gas welding, the WAAM processes, the layers were deposited in both the longitudinal and transverse axes, and with aluminum nitride (AlN) reinforcing ratios of 0%, 2.5%, 5%, and 7.5%, ER4043, a filler wire, was used. ER4043-AlN composite’s dry wear behavior was examined using pin-on-disk testing. The experiments considered different filler deposition orientations and were performed under sliding circumstances with varying reinforcement ratios. The results from the scanning electron microscope research showed that AIN reinforcement was present under all test circumstances. The transverse direction (Y) consistently exhibits higher hardness than the longitudinal direction (X) at each reinforcement level. Transverse composite samples performed better than the rest in terms of wear rate, specific wear rate, and coefficient of friction, as shown in the wear tests.
