Turbine Blade Cladding & Remelting for Single-Crystal Volume Extension

By Irene Alfred, Boris Rottwinkel, Christian Noelke, Volker Wesling, Stefan Kaierle Nickel-based superalloys are used extensively in the combustor and turbine sections of aircraft engines due to their ability to withstand temperatures of up to 1100°C, thereby increasing engine efficiency. The microstructure of single-crystal turbine blades show superior creep and fatigue properties when compared to poly-crystal […]

Internal Bore Laser Cladding

By: Paul Colby Background Bimetallic cylinders are pressure vessels functioning as a component in a system to melt plastics with abrasive additives such as glass and minerals. These vessels have been manufactured the same way since the 1950‘s. Xaloy has developed and patented a new technology that will improve the useful life of bimetallic cylinders […]

Hot Wire Laser Cladding with Solid & Cored Wire

By: Wayne Penn Alabama Laser Hot Wire Laser cladding developed at Alabama Laser along with Lincoln Electric offers improved performance over traditional cladding techniques. Improvements include: no wasted filler material, production repeatability and stable production rates. The deposit has a pure metallurgical chemistry and the base material has a small heat affected zone. Alabama Laser […]
