Extreme High-Speed laser material deposition known by its german acronym (EHLA)
The EHLA process is a patented and award-winning process from the Fraunhofer-Institute for Laser Technology in Aachen. This is a revolutionary approach for the production of corrosion and wear resistant layers. This process is a further development of conventional laser cladding (LC), in which the innovation of the process method is defined by
complete melting of the powder through targeted interaction of radiation and powder particles above the melting bath and
apply in liquid form to the component surface.
Compared to conventional LC, higher process speeds and consequently higher coating rates are possible. Coatings can now be produced faster and more economically, while maintaining the decisive quality features of conventional LC (including metallurgically bonded layers without pores and cracks). The following pictures show the technological and economic advantages of the EHLA-process, which finally enable the process to be used in a large-scale production.
