Press Hardening
Project example electrolytic corrosion
• Development of protective coatings
Issue
- Press hardening is used for the manufacturing of high-strength steel components in the automotive industry
- Without an appropriate protective coating severe scaling occurs at the required working temperatures (>900°C)
- Previous coating systems have various disadvantages (e.g. problems with post-processing such as welding or painting)
Approach
- Development of a multi-layer system using oxide nano-particles, which suppresses scaling and enables good processability of the sheets
Customer Benefit
- Significant reduction in scaling and surface decarburisation during the forming process
- Further processing by means of resistance spot welding and laser welding is possible
