Mitigation for Edge Corrosion Protection for Automotive Bodies 2019-28-2561

A major challenge to automotive industry is to protect the vehicle from corrosion in varying environments with respect to different service conditions. One of the main types of corrosion that affects aesthetic look is edge corrosion on sheet metal. Mostly edge is acting as starting point of corrosion due to unprotected metal exposed to environment. Special attention needs to be given to exposed edges to protect from rust formation.
Samples were prepared as per design of experiments with respect to manufacturing process condition, material usage, and design. These samples were tested for corrosion test and painting process compatibility.
In this study effect and limitation of burr and optimum solution with respect to corrosion was evaluated and results will be discussed.
