Nitrex is gearing up for the SVW Heat Treatment Symposium 2024 on November 20, 2024, in Brugg-Windisch, Switzerland. Now in its third year, this premier event, hosted by the Swiss Heat Treatment Association (SVW), brings together industry leaders from Switzerland, Germany, and Austria for a cross-border exchange of knowledge. Attendees will explore the latest advancements in materials and heat treatment technologies that are reshaping industries such as automotive, aerospace, and precision engineering.

This year, Karl-Michael Winter, VP of Nitrex R&D and Engineering, will spotlight the “New Generation of Nitrocarburized and Post-Oxidized Brake Discs,” emphasizing the pivotal role these treatments play in enhancing automotive brake rotor performance. With the EU’s forthcoming Euro 7 emissions standard set to impose stringent limits on particulate emissions from vehicles, it is crucial to address the corrosion issues associated with traditional cast iron brake discs. These discs are particularly susceptible to rust when not in use, leading to deeper corrosion and increased wear. By utilizing advanced nitrocarburizing processes alongside Smart-ONC® technology, attendees will learn how to achieve exceptional corrosion resistance and significantly extend the lifespan of brake rotors.

Key takeaways from the session will include:

• Exploring how ferritic nitrocarburizing and white layer combinations enhance corrosion resistance in grey cast iron (GCI) brake discs.
• Understanding the impact of white layer thickness, porosity, and post-oxidized layer thickness on corrosion resistance.
• Gaining insights into mitigating corrosion mechanisms like graphitic and pitting corrosion, especially in rear brake systems.
• Learning how machining methods and carbon contents affect corrosion resistance.
• Discovering the effectiveness of Smart-ONC® post-oxidation in creating a protective barrier against damage and failure.

We look forward to meeting you there!
