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.

Systems and methods are provided for viscous and/or chemically erosive flow machining of work pieces. In certain examples, a tool for flow machining may be disclosed. The tool may include a cavity configured to receive a work piece and one or more inlets and outlets for viscous media flow. Viscous media and/or chemically erosive media can be flowed into the cavity and, via a media flow path, can be used to machine the work piece.
