Nuclear power plants, working in extremely harsh environment, primarily in the form of high-
speed fluid flow, circulate through complex systems. Serious tribological problems can occur …

Revealing the fretting failure law and mechanism of steam generator tubes is a critical issue
to ensure the safe operation of nuclear power plants. This paper reviews the current …

The effects of supersonic fine particle bombardment (SFPB) on the wear properties and
surface integrity of 304 stainless steel were investigated. Moreover, the impact of different air …

The effect of fretting frequency on fretting corrosion behavior between Alloy 690TT heat-
exchanger tube and 405 stainless steel plate in simulated secondary water of pressurized …

Repair welding is widely used to repair defects such as fatigue crack and stress corrosion
crack in metal structures for prolonging their service lives. However, the residual stress …

The fretting corrosion testing of A690 with a sliding amplitude of 100 μm and a normal force
of 20 N was conducted in a manually designed equipment with a tube-on-plate contact …

Abstract Inconel 718 (IN718) superalloy specimens were treated with ultrasonic nanocrystal
surface modification (UNSM) at room and high temperatures (RT and HTs). The purpose of …

Fretting experiments of Alloy 690TT tubes against 405 stainless steel (405 SS) plates were
carried out to evaluate the influence of temperature on fretting performance of Alloy 690TT …

The tribocorrosion behaviors of three nickel-based superalloys (Incoloy 800, Incoloy 825,
and Inconel 625) in 3.5 wt% NaCl are studied under the cathodic, natural-corrosive, and …

For understanding the long term fretting mechanism, the effect of normal force on the fretting
wear behavior of 690 TT heat transfer tube against 304 stainless steel (SS) ball in simulated …
