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. 

Euro 7 standard sets new framework conditions for brake disks

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 as a tried and tested process is ready for series production

High-speed laser metal deposition (HS-LMD) makes it possible to reliably produce low-emission brake disks in large series.

With laser metal deposition, the laser generates a weld pool on the component. A metal powder is then continuously added and melted on in this pool. This method can be used to repair components, for example.
