Analysis of the Process Conditions for the Coating of Grey Cast Iron Brake Discs through Laser Material Deposition is now available from Jonathan Schaible, Fraunhofer Institute for Laser Technology ILT., on the EuroBrake website. He answers a few related questions in this Spotlight.
What do you find most interesting about the topic you are presenting on?
Increasing the corrosion and wear behavior of brake discs through applying thin protection layers made by EHLA is a major step towards resource efficiency. Brake discs coated by EHLA have significantly lower wear loss and have a longer product life cycle. In this work, an EHLA layer is compared to an LMD layer, and clear productivity benefits of EHLA can be derived from the higher surface coating rate and higher powder deposition efficiency.
How has coronavirus affected your work and has it had a direct impact on the work you are presenting?
Our research on the presented topic became more digital due to the corona-related short time work in the companies that we are cooperating with. New solutions for the joint process development with our partners were found through installing cameras in our labs and presenting the EHLA process live in the digital meetings.
Who do you think will be most interested in seeing your presentation and who would you most like to ask questions about it?
The Automotive industry, especially OEMs, spare parts manufacturers of brake discs, manufacturers of brake pads; but also system suppliers like manufacturers for lasers, lathes and powder materials.
Jonathan Schaible is a research associate in the Laser Material Deposition Group at Fraunhofer Institute for Laser Technology (ILT) in Aachen. Jonathan studied mechanical engineering at Karlsruhe Institute for Technology (Germany) and Tampere University (Finland), before joining ILT in 2017. Since the end of 2019, he leads the team “System Technology“, focusing on powder feeding equipment, kinematic systems, and robotics. After accompanying the first steps of pushing Extreme High-Speed Laser Material Deposition (EHLA) towards industrial use in brake disk coatings, his current research is aimed at qualifying EHLA for Additive Manufacturing using novel high-speed handling systems and adapted process parameters.
