Experimental analysis of frequency on tensile-compressive fretting fatigue behaviour of Al-Zn-Mg alloy
摘要：Experimental analysis of frequency on tensile-compressive fretting fatigue behaviour of Al-Zn-Mg alloy was studied in this paper. Effect of frequency on fretting fatigue lives, damage characterization and fretting fatigue fractures of Al-Zn-Mg alloy were researched under different frequencies. Factors affect fretting fatigue life and comparison of lives between fatigue and fretting fatigue were discussed. Average scar widths of Al-Zn-Mg alloy at various frequencies, comparison of fretting scars’ oxygen content at various frequency and abrasion loss of Al-Zn-Mg alloy under different frequencies were used to study on influence of frequency on fretting fatigue damage behavior of Al-Zn-Mg alloy. Fretting fatigue crack growth zone in the whole fracture zone were used to study on effect of frequency on fretting fatigue fractures of Al-Zn-Mg alloy.
