Situation:

Tool wear occurs during cutting and forming

• Temperature gradients and deviations
• Mechanical stresses
• Abrasion and surface fatigue

Solution:

• Development of wear protection systems based on chemical nickel dispersion coatings

Operational benefit:

• Reduction of wear
• Increase in service life
• Reduction of the downtimes for tool change
• Reduction of the maintenance time and costs of the tools

The projects funded by the European Union and the state of North Rhine-Westphalia investigate the following topics:

– DisperTherm: wear protective coatings for rolls in long product hot rolling process

– non-stick-FiReNi: the electroless nickel dispersion layers are currently being optimised for use on highly loaded cutting tools
