Press Hardening

Project example electrolytic corrosion
• Development of protective coatings


  • 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)


  • 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
