Running condition and material response fretting maps of incoloy 800 steam generator tubes against AISI 304L pads in air and room temperature
(Elsevier, 2019-07)
Running Condition and Material Response Fretting Maps of Incoloy 800 steam generator tubes against AISI 304 L were determined in air at room temperature. Tests were performed up to 106 cycles using displacement amplitudes ...
Fretting damage of Ni-rich ultrafine grained NiTi superelastic wires
(Elsevier Science, 2019-02)
The effects of fretting on Ni-rich ultra-fine grained NiTi superelastic wires have been characterized. Fretting tests have been performed using wire on wire in 90° cross-cylinder configuration until 105 cycles in air at ...
Stress gradients in fretting fatigue
(2016-02-28)
Launched by the engine manufacturer SNECMA (SAFRAN group), this thesis focuses on the damage by fretting fatigue. The control of this phenomenon is of major importance in determining the lifetime of fan's disc. When two ...
Violet ZnSe/ZnS as an alternative to green CdSe/ZnS in nanocrystal- fluorescent protein FRET systems
(American Chemical Society, 2009-06)
Fluorescent proteins from the green fluorescent protein family strongly interact with CdSe/ZnS and ZnSe/ZnS nanocrystals at neutral pH. Green emitting CdSe/ZnS nanocrystals and red emitting fluorescent protein dTomato ...
Characterization of modified Ti6Al4V alloy after fretting-corrosion tests using near-field microscopy
(Surface and Coatings Technology Volume 212, November 2012, Pages 134-144, 2012-11)
Fretting wear and corrosion of Ti6Al4V alloys at the bone/implant stem interface produce the release of wear particles and corrosive ions from the stem into the surrounding tissue that can induce bone resorption. In this ...

En esta tesis se realiz´o la caracterizaci´on mec´anica y microestructural del da˜no por fretting en tubos de generadores de vapor (TGVs) de la industria nuclear. Se estudiaron tubos de Incoloy 800 (I 800) e Inconel 690 ...
Fretting Damage in Incoloy® 800 Tubes Against Different Support Materials
(Elsevier, 2015-07)
In this work the fretting wear in steam generator tubes of Incoloy® 800 in contact with AISI 304, AISI 1060 and Cu (99,9%) pads acting in a cross-tube geometry was studied. Wear surface was characterized by scanning electron ...
A study of debris and wear damage resulting from fretting of Incoloy 800 steam generator tubes against AISI Type 304 stainless steel
(Elsevier Science Sa, 2016-12-29)
Wear damage and resulting triboparticles corresponding to fretting of Incoloy 800 steam generator tubes against AISI 304 pads were characterized in experiments performed in air at room temperature in a 90° cross cylinder ...
