What is laser metal deposition?

Laser metal deposition is an additive manufacturing process where a laser beam is used to form a melt pool on the surface of a metal object. Metal powder is then injected using a gas stream. A thin layer of the base material is melted by the laser heat source in a controlled way.

How does laser metal deposition work?

Laser metal deposition (LMD) is an additive manufacturing process in which a laser beam forms a melt pool on a metallic substrate, into which powder is fed. The powder melts to form a deposit that is fusion-bonded to the substrate. The required geometry is built up in this way, layer by layer.

What is the meaning of plasma plume?

A vapor–plasma plume consisting of ions, electrons, and vapor particles is generally formed above the workpiece during various types of laser materials processing. The laser beam propagates through this plume before reaching the substrate surface.

What is metallization in IC fabrication?

Metallization is the process by which the components of IC’s are interconnected by aluminium conductor. This process produces a thin-film metal layer that will serve as the required conductor pattern for the interconnection of the various components on the chip.

What is the name of the method used to deposit copper on silicon?

A novel copper deposition method has been developed to plate silicon surfaces. Continuous copper films are obtained galvanically on p- or n-type, single- or polycrystalline silicon.

What does the surface of a metal turn into when it corrodes?

A compound. As when a metal like Iron is corroded by water and air, it just forms a new compound Fe2O3.
