| Abstract Scope |
The design of robust and reliable metals that are simultaneously wear and corrosion resistance is crucial for various applications where high mechanical stress and corrosive environment coexist. Past research mainly relies on costly and trial-and-error experimental methods for alloy design and optimization. In this work, using finite element analysis (FEA) method, a model was developed to investigate and predict the tribocorrosion properties of aluminum alloys using experimentally obtained mechanical and corrosion properties as inputs. The stress-corrosion synergy effects was modeled based on Gutman’s theory which correlates equilibrium corrosion potential with deformation. The model predicted how the electrochemical and mechanical properties of the material could affect the corrosion rate when the sample is under compressive force. The simulated results provided further insights toward the tribocorrosion-resistant alloy design, suggesting that optimizing mechanical properties like elastic modulus and yield strength could also lower corrosion rate when the material undergoes deformation. |
