Laser metal deposition of brake disks in accordance with the Euro -7 standard
Find out why high-speed laser metal deposition is the optimal choice for manufacturing Euro 7-compliant brake disks - and why it could become the new standard in the manufacture of brake disks.
Transforming production processes with high-speed laser metal deposition
Until now, brake disks have mostly been cast and machined in vehicle construction. Untreated cast brake disks cause heavy brake abrasion and high particulate emissions during vehicle use. The new EU standard, Euro 7, significantly reduces the permitted pollutant values and for the first time also sets binding limits for non-exhaust-related particulate matter from tire and brake abrasion. This new legal standard presents brake disk manufacturers with major challenges: They not only have to manufacture an optimized product, but also test new, suitable production technologies and integrate them into their production processes before the deadline.
The good news is that there is already a tried-and-tested process that can be used in large-scale production to manufacture Euro 7-compliant brake disks - high-speed laser metal deposition (HS-LMD). With this process, an extremely thin coating of a high-tensile and abrasion-resistant metal-carbide mixture is applied to the conventional brake disk, which significantly increases the wear and corrosion resistance.
Laser metal deposition offers optimum requirements for meeting the Euro 7 fine dust standard and the associated compliance with the prescribed brake wear.
High-speed laser metal deposition (HS-LMD) makes it possible to reliably produce low-emission brake disks in large series.
