Abstract
A method of smoothing an inner surface of a tubular wall of a workpiece is disclosed, including immersing the workpiece in a mixture of a liquid and an abrasive and inserting a cavitation peening nozzle into a cavity of the workpiece. The method further includes injecting a cavitating jet from the cavitation peening nozzle into the cavity.

A method of smoothing an inner surface of a tubular wall of a workpiece, comprising:
- immersing a workpiece in a mixture of a liquid and an abrasive,
- inserting a cavitation peening nozzle into a cavity of the workpiece, and
- injecting a cavitating jet from the cavitation peening nozzle into the cavity.
An apparatus for smoothing a surface, comprising:
- a first fluid source,
- a cavitation peening nozzle having an external side and a spacing device extending outward from the external side, and
- a conduit connecting the first fluid source to the cavitation peening nozzle, and a pump configured to pump a first fluid from the first fluid source through the conduit to the cavitation peening nozzle, the cavitation peening nozzle being configured to generate a cavitation bubble cloud for smoothing an inner surface of a tubular wall of a workpiece.
An apparatus for smoothing a surface, comprising:
- a fluid source,
- a cavitation peening nozzle,
- a conduit connecting the fluid source to the cavitation peening nozzle,
- a pump configured to pump high pressure fluid from the fluid source through the conduit to the cavitation peening nozzle, the cavitation peening nozzle being configured to generate a cavitation bubble cloud for smoothing an inner surface of a tubular wall of a workpiece, and
- a slurry of a liquid and an abrasive, inside the tubular wall of the workpiece.
