At this year’s EuroBrake, Laserline will be presenting highly efficient laser solutions for the environmentally friendly and economical series coating of brake discs. In addition to coating using 30 kW diode lasers, the focus will also be on double-sided cladding and further improving process efficiency. The diode laser specialist will also be presenting new cladding nozzles for optimizing coating processes.

Laserline presented energy-efficient laser applications for the environmentally friendly series coating of brake discs at EuroBrake (June 17 to 19, 2024, Rheingoldhalle Mainz, stand 15). The main focus will be on coating with a 30 kW diode laser, which enables shorter process runtimes for brake disc coating thanks to its higher power class, as well as double-sided brake disc coating. This process variant makes it possible to process both sides of the workpiece simultaneously, which heats it up more evenly and reduces the likelihood of deformation. Other trade fair highlights include new cladding optics and nozzles that optimize the production process: The Twin-Clad, for example, has two customized spots, which has a positive effect on process stability. The Con-Clad models, on the other hand, allow surface conditioning to be carried out before the actual coating process. A presentation by Dr.-Ing. Thomas Molitor, Manager of Sales General Manufacturing Laserline, on “Optimizing Production Efficiency through High-Power Diode Lasers” on 19 June between 8:30 and 10:20 a.m. in Gutenberg Hall 1 will round off the trade fair presentation. Interested parties will have the opportunity to find out all about the benefits of coating using high-power diode lasers for process efficiency.

Cladding based on diode lasers

The laser coating of brake discs is realized with the help of high-performance diode lasers and combines long-term corrosion and abrasion protection. Neither the standard gray cast iron material nor the brake disc production process need to be adapted. Instead, the coating is applied to the finished brake disc in a final production step in under a minute. This economical and fast process is made possible by the use of high-speed processes, which place hardly any thermal stress on the workpiece and produce very thin yet resistant coatings. This is usually a carbide coating that is applied in less than 20 seconds per layer by moving the disk under the laser beam and powder nozzle at feed rates of up to 400 m/min. As with any laser coating, this creates a highly stable fusion-metallurgical bond between the base and coating material – the high process speed also makes it possible to apply very high laser power without risking component deformation. This means that very robust coatings can be produced from a thickness of around 100 µm. Web: ww.laserline.com/en-int/
