Abstract
A magnesium alloy panel for a vehicle includes a first region and a second region extending from the first region to an edge. The first region has a first microstructure having a first corrosion resistance. The second region has a second microstructure different than the first microstructure and has a second corrosion resistance greater than the first corrosion resistance. A system for mass producing magnesium alloy panels includes a forming apparatus and a laser cutting apparatus. The forming apparatus forms a panel having a first microstructure having a first corrosion resistance. The laser cutting apparatus cuts the panel to form the edge using a laser, and forms the second microstructure while forming the edge. The second microstructure is different than the first microstructure and has a second corrosion resistance greater than the first corrosion resistance. A method for mass producing magnesium alloy panels is also provided.
