The differences in the forming behaviour of metallic coated steel sheets compared to uncoated sheets causes problems like wear, adhesion, abrasion, powdering and flaking at deep drawing of metallic coated sheets. This project aims to improve the forming behaviour of steel sheets with electrogalvanized zinc coating ZE, hot-dip galvanized coating Z and galvannealed coating ZF by investigating different posttreatment systems. The posttreatment systems to be examined are phosphating, prelubes, dry lubricants (temporary organic coatings) and organic flash coatings that would be compatible with the customers phosphating and painting systems. Laboratory applications of different posttreatments will be followed by corrosion protection and tribological experiments. The forming behaviour of steel sheets with posttreatments will be evaluated and should lead to recommendations of optimized sheet/posttreatment combinations.
