A Review of Research Progress on the Fretting Fatigue Mechanism and Protection Measures of Metal Matrix Composites

The performance characteristics of metal matrix composites (MMCs) and the need to study their fretting fatigue wear during service are discussed. Four main elements MMCs (aluminum, copper, titanium, iron, magnesium, nickel, etc.) These factors influencing fatigue, mechanism research, life prediction, development process protection methods, respectively. Factors such as internal crack nucleation development, loading conditions, working environment analyzed trend research is outlined from several perspectives mechanism, methods. In particular, current state results achieved highlighted, some issues that remain be studied illustrated. combined effects fretting, wear, accuracy applicability dispersion strengthening phase, interface problems themselves, etc., all further research. review summarizes existing provides reference help for subsequent developments.
