CWJP : Cavitation Water Jet Peening Technology

Features
Clean processing method
Shotless peening using only water.
It is a modern clean processing method that generates no industrial waste.
Additionally, since no media is used, washing or polishing in subsequent processes is not required.
The risk of contamination can also be minimized.
Broad applicable range
Unlike shot peening, which can only be applied to areas where the media makes contact, CWJP can perform peening in the path of the cavitation jet flow.
Furthermore, there is a characteristic that the areas downstream of the cavitation jet flow are more responsive to stress.
Does not roughen the processed surface.
Peening with water jet can be performed without marring the processed surface.
There is no edge formation on the processed area, allowing for stable extension of the component’s lifespan.
Does not alter toughness
It is a distinctive method that refines and densifies the microstructure, enhancing hardness while maintaining the material’s inherent toughness.
Peening can also be performed on small-diameter components.
Since the cavitation bubbles used for peening are very small, it can be applied to various components, including small-diameter parts.
Traditionally, small-diameter components and intricate areas were limited by media size, but with CWJP, peening is possible.
