Plasma Wire Deposition

Definition

Plasma wire deposition is a manufacturing process that uses a plasma arc to melt a metal wire, which is then deposited onto a substrate to create a coating or part. This technique combines the advantages of plasma technology and wire feed methods, allowing for precise control over material properties, thickness, and microstructure of the deposited layer. It's widely used in applications such as repair, surface enhancement, and additive manufacturing.
