Fatigue performance is critical for aerospace fan and turbine blades. Wet shot peening offers a proven way to extend component life while overcoming many of the limitations of traditional dry systems.
By projecting spherical media in a water slurry, wet peening introduces beneficial compressive stresses into blade surfaces. The result:
• Improved fatigue strength and resistance to cracking
• Greater durability under bending and twisting loads
• Lifespan extensions reported at over 1000% in turbine applications
So why choose wet over dry shot peening?
• Peening to the same intesity as dry shot peening
• Superior, more consistent surface finish
• No dust contamination or post-process clean-up
• No need for pre-cleaning oil and grease
• Reduced HSE risks, particularly when processing titanium and reactive alloys
• Lower media consumption through closed-loop filtration and recycling
The Cougar+ vertical auto. wet blasting machine brings this together with aerospace-grade process control. It offers:
• Large pull out turntable for easy loading
• Multi-gun configurations for full coverage and productivity
• Integrated HMI with precise parameter control
• Hydrocyclone and sediment tank filtration for consistent media quality
For MRO and OEM environments, that means repeatable intensity, cleaner processing and reduced total cost of ownership compared with legacy dry shot peening systems.
If you are reviewing your blade strengthening process, is dry shot peening still delivering the control and cleanliness your operation demands?
