ABSTRACT
Compressive residual stress is one of the surface characteristic resulting from shot peening, but it can be an error to focus only on it.
Depending on the application (fatigue, pitting, micro-pitting, fretting, stress corrosion cracking) there are others characteristics which must be considered with attention
when we specify shot peening parameters (shot nature, shot size, shot hardness, Almen intensity, shot angle, coverage). These surface characteristics are elimination of tool
marks or surface defects, modification of surface roughness, work hardening, surface elongation, contamination, surface damages. This paper describe the most important of
them.
