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.
