The Zr-4 alloy tubes in nuclear fuel rods in pressurized water reactor (PWR) fuel assemblies
were subjected to bi-directional composite fretting wear tests with different phase differences …

In this work, GH4169 dovetail specimens were coated on both sides with a bonded solid
lubricant coating. Fretting fatigue tests were carried out at 500° C and compared with …

Cr-based coatings are promising candidates to protect the claddings on accident-tolerant
fuel (ATF) rods in pressurized water reactors (PWRs). In this study, the effect of water …

The present research work deals with the fatigue assessment of an Al 7075-T651 subjected
to fretting fatigue testing characterised by cylindrical contact. A small rolling of the pads is …

A Zr-4 alloy tube versus Zr-4 alloy spring contact was subjected to conventional sinusoidal
fretting and random fretting under various tribological conditions. In this exploratory work, the …

Tribological studies, crucial in understanding the complex interactions between surfaces in
relative motion, necessitate the use of diverse tribometers to explore a wide range of …

Fluorocarbon resin (FC), as a commonly used topcoat material for coating systems, is
susceptible to the combined effects of seawater corrosion and ocean current erosion when …

In this paper, the fretting wear mechanism of the directionally solidified superalloy (DZ125)
surface created by wire electrical discharge machining (WEDM) are studied. Samples with …

The Cr (chromium) based coating is the most simple, studied, and promising coating for the
accident-tolerant fuel cladding of pressurized water reactors. In this work, special tangential …

The fretting wear behavior of Zr-1Nb alloy cladding tubes under different tangential
displacement amplitudes under grid-to-rod contact conditions was investigated. The …
