Cavitation Water Jet Peening
High pressure water is jetted into the water at high speed from a special cavitation-promoting (air bubble) nozzle to cause cavitation, and GPa (gigapascal) class impact force when bubbles collapse near the workpiece produces a peening effect.
Increased fatigue strength:
Applying compressive stress to a depth of about 1mm from the surface.
Improves fatigue strength and life.
Clean processing method:
Shotless processing method using only water, no cleaning process required.
Strength and long life:
Increased fatigue strength of steel and aluminum alloys
Prevention of stress corrosion cracking:
Welded parts of structures
Removal of undissolved surface, surface finish:
Post processing for additive manufacturing part
Improved Fatigue Strength
A clean processing method
Shotless processing method
Uses only water
No cleaning process required
