Initiation of fretting fatigue scar of Ti-6Al-4V alloy dependent on the influence of its surface roughness [PDF]

Jurnal Tribologi, 2018
This paper reports on the experimental studies undertaken to detect the early stage when appears the fretting wear of the Ti-6Al-4V alloy used for the hip prostheses. Wear is a critical aspect for estimating the fretting fatigue.

Multiscale analysis of the effect of debris on fretting wear process using a semi-concurrent method [PDF]

, 2020
Fretting wear is a phenomenon, in which wear happens between two oscillatory moving contact surfaces in microscale amplitude. In this paper, the effect of debris between pad and specimen is analyzed by using a semi-concurrent multiscale method.

Comparative study on fretting wear damage mechanisms of 316L steel in dry air and liquid lead-bismuth eutectic environments

Journal of Materials Research and Technology
Due to flow induced vibration caused by coolant circulation, fretting wear inevitably occurs between fuel cladding, heat exchanger tubes and their holders in Gen IV lead-bismuth eutectic (LBE) cooled nuclear reactors.

Fretting Corrosion Performance Evaluation of Uncoated Cladding, Cr Coating Cladding and AlCrNbSiTi Coating Cladding

Alloys, 2023
In pressurized water reactors (PWRs), flow-induced vibration (FIV) induces the fretting wear of fuel rods and supporting grids, and the process is accompanied by corrosion, which is called fretting corrosion. In this paper, fretting corrosion experiments

‘Where are the adults?’: Troubling child‐activism and children's political participation

British Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...
