Peening of airplane engine parts
What is Wet Peening?
The wet peening method is a new shot peening method, where wet blasting is used with a “wide gun,” our unique and patented wet blasting gun.
What is Peening?
This is a surface treatment by forging or peening; like hitting the metal surface with a round-head hammer.
Shot-peening is a surface treatment method for improving the mechanical characteristics of material surfaces by hitting innumerable spherical particles on metal surfaces:
- Applying residual compressive stress to the materials.
- Making plastic deformation and surface hardening to the work piece surface.
About our wide gun, the core technology of the wet-peening method.
- Slit-shaped nozzle cross section.
- Uniform processing power to the whole surface.
Differences compared with conventional guns/nozzlesDifference of projection patterns
Peening intensity is the strongest at the center and it becomes weaker as it comes to periphery area.
Projection power is uniform to the whole area in the direction of slip length except for both ends.
