Critical analysis of processes and apparatus for industrial surface peening technologies

The objective of this study is to review and evaluate the applications of surface peening processes that can significantly contribute to surface property enhancement and prevent surface-induced failures. In the study, taking account of industrial applications, the current advantages, limitations, technological barriers and future prospects of peening technologies for industrial applications is assessed. Detailed explanations of the recent developments in the main components of peening processes are given. Factors such as peening media, peening process, component geometry, manufacturing method and mechanical properties of the base material are studied using experimental data. Developments in peening processes improved fatigue, corrosion and fretting behaviours of high performance components such as titanium alloy connecting rods for titanium alloy connecting rods for sports car. The results of the study conclude that peening processes have no geometry limitations and produce results that are usually economical.
