Abstract Scope |
Friction Stir Welding (FSW) is now being used widely in designing vehicle parts. The next generation FSW Magnesium-Aluminum Vehicle Joints are up to 50% lighter than steel-based alloy, which can be much more energy saving. While the biggest challenge of FSW MG-AL Alloy is the galvanic corrosion between dissimilar metals. Cyclic Corrosion Test (CCT), based on the SAE J2334 standard, provides a more realistic exposure method to observe the corrosion change between them. Linear polarization resistance (LPR) as well as galvanic corrosion tests (ASTM-G71) will be used qualitatively to compare with the result of CCT. Scanning Electron Microscopy (SEM-EDS) will also be used to characterize the surface transformation. |
