Modification of fretting fatigue behavior of AL7075–T6 alloy by the application of titanium coating using IBED technique and shot peening
In this work, improvement in fretting fatigue life of AL7075–T6 has been investigated by titanium surface coating using ion-beam-enhanced deposition (IBED) technique and shot peening. From the experiments, the following conclusions were derived: (i) Shot peening increased the fretting fatigue life u...

description | In this work, improvement in fretting fatigue life of AL7075–T6 has been investigated by titanium surface coating using ion-beam-enhanced deposition (IBED) technique and shot peening. From the experiments, the following conclusions were derived: (i) Shot peening increased the fretting fatigue life up to 350%. (ii) Titanium coating increased the fatigue life up to 100% with respect to virgin specimens for low working stresses, while it reduced the fatigue life at higher working stresses significantly. (iii) Titanium coating+shot peening increased the fatigue life up to 130% with respect to the virgin specimens for low working stresses, while it reduced the fatigue life at higher working stresses significantly. The highest and the lowest increase in coefficient of friction are obtained for virgin and shot-peened+titanium-coated specimens, respectively. IBED surface-modification technique is not successful in reducing fretting fatigue, except at low stresses. |
