An apparatus for treating a surface of an object is disclosed, including a carrier configured to transport the object through a treatment zone and an array of nozzle devices, each nozzle device positioned to deliver a cavitating jet into the treatment zone. The apparatus further includes a fluid source, a pump connected to the fluid source, and a hose configured to carry fluid under high pressure generated by the pump from the fluid source to the array of nozzle devices.

Automated cavitation processing

A cavitation nozzle is disclosed, including a plate, a hollow body, and a cap removably engaged with the hollow body and holding the plate against a distal end of the hollow body. The plate may have a central aperture and a distal surface, wherein the distal surface is bisected by a groove and the hollow body is configured to deliver high pressure fluid through the central aperture. The delivered high pressure fluid may be discharged as a cavitating jet.

Damage tolerant cavitation nozzle

A cavitation peening system is disclosed, including a tank containing a fluid, a carrier, and an array of cavitation nozzles. The carrier is configured to deliver a workpiece to a treatment zone in the tank, and the array of cavitation nozzles are collectively configured to generate a cavitation induced whirlpool in the treatment zone.

A metallic structure includes a metallic sheet, including a metallic-sheet first surface and a metallic-sheet second surface. The metallic structure includes a metallic doubler, extending from the metallic-sheet first surface, and a first junction between the metallic-sheet first surface and the metallic doubler. The metallic structure includes a metallic article, extending from the metallic-sheet second surface, and a second junction between the metallic-sheet second surface and the metallic article. The first junction has a first-junction boundary. The second junction has a second-junction boundary. When viewed at any point along the second-junction boundary in a direction, perpendicular to the metallic-sheet first surface, the second-junction boundary does not extend outside of the first-junction boundary. In a plane, intersecting the metallic doubler and perpendicular to the metallic-sheet first surface, the metallic doubler has at least a first doubler thickness and a second doubler thickness, which is less than the first doubler thickness.

Metallic structures with additively manufactured metallic articles and methods for fabrication

Disclosed herein is a system for surface treating an internal surface of a part. The system comprises a tank within which the part is locatable. The system also comprises a fluid within the tank and capable of submersing the part when the part is located within the tank. The system further comprises a nozzle submersed in the fluid and configured to generate a stream of cavitated fluid directed in a first direction. The system additionally comprises a deflection tool submersed in the fluid and comprising a deflection surface that redirects the stream of cavitated fluid from the first direction to a second direction. The first direction is away from the internal surface of the part and the second direction is toward the internal surface of the part.

Implementations are provided for fabricating a finished workpiece having a shaped portion. One implementation includes: a superplastic formation diffusion bonding (SPFDB) component; a cold spray additive manufacturing (CSAM) component; and a mold having a concavity. Various configurations can operate on a workpiece with the SPFDB and CSAM components in different orders. An implementation is configured to cold spray (with the CSAM component) an additive material onto the workpiece; and perform superplastic forming (with the SPFDB component) on the workpiece with the mold, thereby rendering the workpiece into the finished workpiece having the shaped portion. The shaped portion conforms to a shape defined by the concavity. Cold spraying results in an increased thickness of the finished workpiece in a target region, which can provide structural reinforcement, and which can have a tapered edge. The workpiece can be a metal substrate made of titanium, aluminum, stainless steel, or another material.

Systems and methods for cold spray additive manufacture with superplastic formation diffusion bonding

A method of cavitation peening may include coupling a moveable water source to a portable nozzle, through a flexible conduit. The method may include positioning the nozzle adjacent a treatment surface and discharging a first and second stream of fluid through a first and second channel of the nozzle, with the second channel concentrically positioned around the first channel. The first stream may have a first pressure, and the second stream may have a second pressure, the first pressure being greater than the second pressure and the two streams combining to generate a cloud of cavitation bubbles.

Portable cavitation peening method and apparatus

Systems for managing abrasive media in cavitated fluid include a set of sensors in communication with cavitated fluid in a processing tank and a processor coupled to the set of sensors. The processor is configured to determine a density of an abrasive media in the cavitated fluid in the processing tank and facilitate maintaining the density of abrasive media in the cavitated fluid in the processing tank at a level that is greater than or equal to a threshold level of abrasive media. The processor is further configured to command the abrasive media addition device to add the recycled abrasive media to the processing tank to increase the density of abrasive media in the cavitated fluid in response to determining that an average density of abrasive media is less than the threshold density of abrasive media.

Systems and methods for inspecting additively manufactured components

A component is formed by welding a plurality of sheets of metal to form a blank with a number of weld nuggets, placing the blank between a die section and a lid section, heating the die section to heat the blank, and introducing a pressurized gas between the lid section and the die section to press the blank into a mold in the die section to form a component. The number of weld nuggets has a desired thickness ratio between about 1.1 to about 1.25 such that the plurality of sheets of metal and the component formed have a number of characteristics that are substantially the same.
