Do ceramic femoral heads reduce taper fretting corrosion in hip arthroplasty? A retrieval study. [PDF]

Clin Orthop Relat Res, 2013
BACKGROUND: Previous studies regarding modular head-neck taper corrosion were largely based on cobalt chrome (CoCr) alloy femoral heads. Less is known about head-neck taper corrosion with ceramic femoral heads.

Fretting Corrosion Behavior of Additive Manufactured and Cryogenic-Machined Ti6Al4V for Biomedical Applications [PDF]

, 2016
Metal ion release, caused by synergistic effect of wear and corrosion, is one of the major concerns related to the prostheses lifetime. In this work, samples of additive manufactured Ti6Al4V are machined under dry cutting and cryogenic cooling conditions

Development of a Wöhler-like approach to quantify the Ti(CxNy) coatings durability under oscillating sliding conditions [PDF]

, 2005
The selection of a proper material for the particular engineering application is a complex problem, as different materials offer unique properties and it is not possible to gather all useful characteristics in a single one. Hence, employment of different

Method for Characterization of Material Loss from Modular Head-Stem Taper Surfaces of Hip Replacement Devices [PDF]

, 2015
Assessment of the head-stem taper junction requires the estimation of material loss from the taper surfaces of both femoral head and stem. This paper describes a method for the measurement and analysis of material loss from the modular taper junction of ...

Fretting corrosion behavior of nitinol spinal rods in conjunction with titanium pedicle screws [PDF]

, 2017
Untypical corrosion damage including erosions combined with the build-up of titanium oxide as a corrosion product on the surface of explanted Nitinol spinal rods in the areas where it was in contact with titanium pedicle screw head is reported.

Heat Treated NiP–SiC Composite Coatings: Elaboration and Tribocorrosion Behaviour in NaCl Solution [PDF]

, 2009
Tribocorrosion behaviour of heat-treated NiP and NiP–SiC composite coatings was investigated in a 0.6 M NaCl solution. The tribocorrosion tests were performed in a linear sliding tribometer with an electrochemical cell interface.

Improved micro-contact resistance model that considers material deformation, electron transport and thin film characteristics [PDF]

, 2009
This paper reports on an improved analytic model forpredicting micro-contact resistance needed for designing microelectro-mechanical systems (MEMS) switches. The originalmodel had two primary considerations: 1) contact materialdeformation (i.e.

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 ...
