Abstract Scope |
Extreme High-speed Laser Application (EHLA) is an emerging metallic powder deposition process that stems from laser directed energy deposition (L-DED). Developed as a leading surface coating technology for rotationally symmetric components, most notably for brake rotors, turbomachinery and hydraulic cylinders. EHLA can deposit at speeds of several hundred metres per minute and presents the first fusion process that can apply thin coatings in the range of 50-250 micrometres, which is a capability space conventionally serviced by thermal spray and plating techniques. EHLA is disrupting the status quo, thanks to several traits that make it both technologically and commercially advantageous.
With the advancement of new kinematic machines, EHLA can also be realized for freeform manufacturing opportunities including additive manufacturing, dissimilar material joining, repair, and complex surfaces.
Research is presented on the major steps made to realizing this impactful solution. Alloys investigated include nickel superalloys and titanium for aerospace manufacturing. |
