Three-dimensional numerical simulation of micro-galvanic corrosion in 304 stainless steel weld microstructures

Key Points

• Micro-galvanic corrosion occurs in weld microstructures, leading to material degradation.
• Simulation results indicate that localized corrosion rates can vary significantly in different microstructural regions.
• Analysis involved three-dimensional numerical simulations to model the electrochemical behavior of stainless steel.
• Findings suggest the need for advanced protective measures in welded stainless steel applications to enhance corrosion resistance.
