Abstract: (2 Views)
In this study, the corrosion behavior of duplex stainless steel weld cladded on an A283 low-carbon steel
substrate was systematically investigated. The weld cladding was fabricated via the Gas Tungsten Arc
Welding (GTAW) process using ER2209 filler wire. During welding, controlled electromagnetic
vibrations with frequencies ranging from 0 to 100 Hz were applied to the specimens. Microstructural
characterization revealed that both the application of electromagnetic vibrations and the increase in
vibration frequency promoted grain refinement and enhanced the volume fraction of austenite within
the weld cladding microstructure. Electrochemical cyclic polarization tests in a 3.5 wt.% NaCl solution
were conducted to assess the corrosion performance. The results demonstrated that the specimen
welded without vibration exhibited superior corrosion resistance compared with those subjected to
vibration. This deterioration in corrosion performance was attributed to the increased austenite fraction
induced by vibration, leading to a higher density of austenite/ferrite interfaces, which act as preferential
sites for pit initiation, as well as an increased presence of secondary austenite. Furthermore, a positive
correlation was observed between vibration intensity and pit density, indicating that stronger
electromagnetic excitation exacerbates localized corrosion susceptibility
