Fretting corrosion characteristics of NC30Fe alloy in a sodium chloride solution

open access: yes工程科学学报, 2015
By adding an electrochemical test system on a PLINT fretting wear test machine,the fretting corrosion behavior of an NC30 Fe heat transfer tube in a sodium chloride solution was investigated using cross-contacting configuration under different loading ...

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

open access: yes, 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 ...

An ad-hoc fretting wear tribotester design for thin steel wires

open access: yesMATEC Web of Conferences, 2018
Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an increase of the stress field and the following

Effect of Heat Treatments on the Fretting Wear Characteristics of Laser Metal-Deposited Inconel 718

open access: yesMachines
In view of the potential fretting wear issues of Laser Metal Deposition (LMD) In718 in engineering applications, this paper investigates the fretting wear behavior of LMD In718 alloy subjected to two different heat treatment processes: homogenized ...

A computational approach to fretting wear prediction at the head-stem taper junction of total hip replacements [PDF]

open access: yes
Wear is one of the main reasons for failure of modular total hip replacements. Recent evidence suggests that fretting wear occurs at the taper junction which provides fixation between the prosthesis femoral head and stem components.
