Solid state deposition for cosmetic enhancement of anodized friction stir processed parts

摘要

The described embodiments relate generally to methods to enhance cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by the friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line in with a cosmetic surface portion of friction stir processed parts. In some embodiments cold spray can be used to on its own to create a cosmetic join between various parts.

1. A method using a plurality of particles to form a joint that combines a first substrate with a second substrate, the method comprising:
friction stir welding the first substrate with the second substrate at an interface region, the friction stir welding forming a weld line within the interface region; machining a channel in the interface region that includes the weld line and that extends into the first and second substrates; and applying a plurality of particles to form a coating that fills the channel, the plurality of particles formed from a material such that the plurality of particles deform upon impact.
