| Abstract: | Shot peening is a widely applied process for surface modification of materials because of its salient features such as easy operation, low energy consumption, high efficiency and broad suitability.Recent developments on increase of frictional wear by micro particle bombarding and powder impact plating, as far as surface nanocrystallization and simplifying of nitrogen treatment by high energy / ultrasonic shot peening were reviewed. Progresses in dynamic simulation of shot peening process were also summarized. Finally further research on dynamic properties of materials was emphasized by means of engineering calculation method serving for shot peening technique. |
