Prévision de l'épaisseur du film passif d'un acier inoxydable 316L soumis au fretting corrosion grâce au Point Defect Model, PDM Predicting the steady state thickness of passive films with the Point Defect Model in fretting corrosion experiments

MATEC Web of Conferences, 2013
Les implants orthopédiques de hanche ont une durée de vie d'environ 15 ans. Par exemple, la tige fémorale d'un tel implant peut être réalisée en acier inoxydable 316L ou 316LN.

A crack-like notch analogue for a safe-life fretting fatigue design methodology [PDF]

, 2003
Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate ...

Fretting corrosion of hafnium in simulated body fluids. [PDF]

, 2014
Hafnium has been suggested as an interesting material for biomedical applications due to its good biocompatibility and osteogenesis. However, its behaviour under fretting corrosion conditions, found in applications such as dental and joint implants, has ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Low‐Dimensional Materials and Van Der Waals Heterostructures for Energy Application: A Comprehensive Review

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Low‐dimensional materials (0D, 1D, and 2D) exhibit unique electronic and physicochemical properties, enabling advanced nanoelectronic and optoelectronic devices. Mixed‐dimensional heterostructures combine these materials to enhance functionality.

Predicting the steady state thickness of passive films in order to prevent degradations of implant [PDF]

, 2013
Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un ...

Fretting wear of Ti(CxNy) PVD coatings under variable environmental conditions [PDF]

, 2006
Fretting wear as a specific type of degradation is defined as an oscillatory motion at small amplitude between two nominally stationary solid bodies in mutual contact.

Knee arthroplasty failure is associated with significant systemic multimetal exposure

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study investigated whether patients scheduled for revision total knee arthroplasty (TKA) are systemically exposed to arthroplasty metals, and whether systemic metal levels in these patients differ depending on the implants' levels of constraint.

THE CRITERIA OF EXTENDED TENSION IN THE FRETTING PHENOMENON [PDF]

Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019
Fretting is now fully identified as a small amplitude oscillatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e. fretting-wear, frettingfatigue and fretting corrosion.
