Abstract:
Shot peening was recognized over a half century ago as a very economical way to extend the service life of automotive engine valve springs. Today "controlled shot peening"
has developed into a advanced process regularly specified to prevent or to delay metal fatigue cracking and stress corrosion cracking (SCC) in the automotive, aerospace,
chemical, petroleum, power generation and other industries. Peen forming, a related process, is also widely used to shape the complex aerodynamic contour of aircraft wing
skins. More recently, "peen texturing" has found a niche in providing aesthentically pleasing finishes on decorative and architectual metals. Shot peening is not "shot or
grit blasting" which are processes used to remove deposits or mill scale from surfaces. The applications for shot peening are much more demanding and require a process that
is predicatable, uniform and repeatable. While controlled shot peening is considered a mature process, it comtinues to evolve and gain ever increasing acceptance.
