Shot Peening Analysis
What is Shot Peening?
The process of shot peening consists of bombarding a metal surface with glass, ceramic, or aluminum beads, and cut wire.
What Does Shot Peening Do?
Peening causes the material in the surface zone to yield by literally shaking the metal grains into a more relaxed state. Thus, a thin layer of the surface is placed in uniform compression. This compressively-stressed "skin" counteracts tensile stresses and effectively prevents cracking.
Why is Shot Peening Needed?
Machining and forming metal parts creates stress concentrations internally (burrs, scratches, welds, etc.) and may cause additional defects.
These problems may be responsible for premature fatigue failure, porosity, loss of strength and corrosion, but can be prevented through the use of shot peening.
Since fatigue cracks generally begin at surface imperfections, a compressively-stressed, shot peened skin is highly effective in preventing crack formation and growth.
Blast Finishing and shot peening are state-of-the art technology that deburr, clean and enhance appearance. Shot peening can even improve the fatigue life of parts such as: gears, housings, and shafts.
Through our Shot Peening Job Services Program, Engineered Abrasives has the ability to analyze a particular part and enhance its appearance and fatigue life with a Blast Finishing and Shot Peening process.
Engineered Abrasives is committed to the highest standards in the industry, such as the SAE International standards. We are certified for ISO/TS 16949, registered in ISO 14001, approved in Ford Q1, and have patents.
