Laser Metal Deposition (LMD), also known as Direct Energy Deposition (DED) is an often-used technology for high quality repairs, wear and corrosion protection as well as modifications on existing parts. With build-up rates of up to 500 cm³/min this technology can be used for fast, near net shape build-ups for e.g. applying optimized structural reinforcements to increase functionality or resistance to high local stress loads. A new variant of the well-known LMD process is the High-Speed Laser Cladding, enabling very high feed rates between 100-500 m/min and locally adjusted layer thicknesses between 50-300 µm per layer.
For automotive industry, LMD and High-Speed Laser Cladding are already being investigated for a broad range of applications. In the poster, we will highlight use cases from R&D and future production, in particular focusing on the coating of brake discs using High-Speed Laser Cladding.
