Metal coating and cladding techniques employ high temperatures to melt the metal particles which can undermine the integrity and stability of the resulting deposit material and substrate. This paper introduces a new process for the deposition of metallic coatings in the solid state using a supersonic particle stream in conjunction with laser energy input, named Laser Assisted Material Spray, LAMS.

This article presents investigations carried out on the generation of Inconel718-TA6V graded structures by laser cladding. First, we introduce the global context of the project in term of challenge and environment. The study is decomposed into to main tasks : the development of the specific procedure for ensuring a sound TA6V-Inco718 transition, and numerical simulations that will predict information on the thermal...$28.00

Laser Powder Deposition (LPD) for component repair and manufacturing offers some unique solutions for Aerospace applications. LPD is a CAD/CAM solid freeform fabrication technology that uses metal powder and laser fusion for repairing or manufacturing of components. Inherent to LPD is the ability to add material for repair or manufacture of critical GTE components with minimal heat affect to the under lying material. Also, d...$28.00

Laser Percussion Drilling of Aerospace Material

Presented at ICALEO 2006
Aerospace gas turbines require large number small diameter holes (<1mm) to provide cooling in the turbine blades, nozzle guide vanes, combustion chambers and afterburner. Many thousands of holes are introduced in the surface of these components to allow a film of cooling air to flow over the component. Film cooling both extends the life of the component and enables extra performance to be achieved from the engine. Drilling these holes by pulsed Nd: YAG laser is now well established. Such holes can be successfully produced by laser trepanning, but this is relativ...$28.00
