Abstract:  
Controlled steel shot peening - a process used widely in the aerospace and automotive industries to enhance the fatigue life and reduce stress corrosion cracking of critical engine, structural and transmission components - is being employed by USF Vacu-Blast to optimize the inherent strength of stainless steel and titanium surgical implants, such as the artificial hip joint pictured here. This has a shot peened shank and shoulder, which is inserted into the femur, and a highly polished ball joint.
