Shot peening involves striking a surface with spherical blasts and other methods—using glass, metallic or ceramic beads—with enough force to create deformation. The end result is a stronger surface and reduced potential for cracking on the surface. At Cadorath, the method is used extensively on aerospace components to mitigate stressors caused by grinding, local blending or abnormal wear.
ADVANTAGES OF SHOT PEEN
- A manual and automated process that provides consistency in its application.
- Leaves a smooth, but indented, surface finish.
- May hide critical surface issues not visible.
- Creates a uniformly textured, finished surface that increases strength, durability and longevity.
- Induces “healthy” metal stress to help spread the load of wear and embrittlement across a larger surface area.
ORIGINS AND DEVELOPMENT
Shot peening is an ancient art that would have been referred to in earlier times as hammer hardening. The technique was originally used for weapons such as spear heads and copper breast plates. In the 19th and 20th centuries, the process was greatly refined for industrial applications.
New developments and improvements to the technique ensure substrates using the technique are properly prepared for plating. The end result is old or damaged parts looking like new and fresh parts smoothed and strengthened.
