SYSTEMS, DEVICES, AND METHODS FOR SURFACE PREPARATION FOR BOND ENHANCEMENT IN ADDITIVE DEPOSITION PROCESSES

Abstract: an additive friction stir deposition device is provided. in one aspect, the device includes a shoulder configured to rotate about a central axis. the shoulder includes a channel extending from a first end of the shoulder to a second end of the shoulder. the channel allows a filler material to pass through the shoulder from the first end towards the second end. the shoulder configured to deposit the filler material as the device is advanced along a deposition surface. the device also includes a wire brush skirt configured to co-rotate with the shoulder and contact the deposition surface as the device is advanced along the deposition surface. the device also includes a gas shroud configured to direct pressurized gas toward the deposition surface and remove contaminants as the device is advanced along the deposition surface.
