System and method for manufacturing magnesium body panels with improved corrosion resistance

摘要

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.

1. A manufacturing system for mass producing magnesium alloy panels, comprising: a forming apparatus configured to form a panel comprising magnesium having a three dimensional shape and a first corrosion resistance; and a laser cutting apparatus comprising a laser and a feeding apparatus, wherein the laser is configured to cut the panel to form an edge comprising a molten material, and the feeding apparatus is configured to introduce an alloying element as a solid wire to the molten material adjacent to a region of the panel where the laser cuts so as to create an intermetallic phase in the region to provide a second corrosion resistance greater than the first corrosion resistance.
