Abstract:  
Ceramic shot was introduced in 1981. Since then, its use has been developing, particularly on materials such as stainless steel and non ferrous alloys, for example aluminium and titanium alloys in the aerospace industry. The peening properties of the shot stem from the chemical and physical characteristics of the ceramic material. Consolidated experimental and industrial data show that ceramic shot presents a very low breakage. Because of its density, the Almen intensities obtained with ceramic are intermediate to those obtained with steel shot or glass beads. Surface finishing benefits from the low breakage and non polluting characeristics. Two studies on fatigue strength are referred to: one deals with titanium alloy parts and the other with hard steel.
