Fretting wear in aluminium alloy AA5754 joined by self-pierce riveting (SPR), a relatively new fastening technique increasingly used in vehicle structures, has been investigated in this paper. Surface damages have been induced when a joint experienced a sinusoidal cyclic tension-tension load. Various degradation zones have been characterised in the contact surfaces between the aluminium sheets,...

The long-term goal of this research is to identify the dominant mechanisms that control the dynamic tension in submerged cables. This goal addresses the need to suppress or alleviate the dynamic component of cable tension that may adversely affect the performance of underwater cables and any mission they are used to support. For instance, large dynamic tension forces may degrade the positioning...

Abstract Both wear and fatigue occur in fretting condition, they interact with one another during the whole process. Fretting is commonly analysed without considering effect of partial slip regime, although affects lifetime crack initiation. This paper investigates, for first time, debris on To investigate debris, characteristics regime are loading conditions. Then, initiation investigated usin...

The effect of the ultrasonic surface rolling process (USRP) on the rotary bending fretting fatigue (FF) of Ti-6Al-4V alloy was investigated. The reason for the USRP's ability to improve the FF resistance of Ti-6Al-4V alloy was studied. The results revealed that the USRP induced a compressive residual stress field with a depth of 530 μm and a maximum residual stress of -930 MPa. Moreover, the su...

Nb, Ta, and Zr are the favorable nontoxic and allergy-free alloying elements suitable for use in titanium alloys for biomedical applications. Low-rigidity titanium alloys composed of nontoxic and allergy-free elements are receiving considerable attention. The advantage of low-rigidity titanium alloys in the healing of bone fracture and bone remodeling is successfully proven by using tibia of ra...

This article investigates the effect of contact ageing on fretting damage of an epoxy-based cathodic electro-deposited coating for use on automotive seat slide tracks (made of cold-rolled high strength steel). Static normal load was induced at the contact between the coating and an AISI52100 ball for a certain duration. It was identified that plastically deformed contact area increased logarith...

In recent years, there has been considerable interest in investigating the effects of fretting, a common problem of significant practical importance that can affect a wide range of electrical equipment incurring costly component replacement and expensive equipment downtime. Fretting is defined as accelerated surface damage occurring at the interface of contacting materials subjected to small os...
