“…3), conceived and developed in collaboration between ENSM-SE and Böse, was used for fretting-corrosion tests. An electromagnetic motor, first tried for fretting-corrosion, let us obtain the same results as those delivered by the device used previously [9][10][11]. The load cell is a piezoelectric transducer and the displacement measurer is a capacitive sensor.…”

In biomedical field, fretting-corrosion between 316L SS femoral stem and bone cement is one of the significant causes of the hip prosthesis loosening. This article investigates wear by fretting-corrosion at the contact between 316L and PMMA . The influences of the ionic strength (NaCl solutions from 10 -3 to 1 mol.L -1 ), a model protein (albumin) and electrochemical conditions on contact behaviour are studied. At OCP (Open Circuit Potential) conditions, the chlorides concentration, i.e. the ionic strength, increases the 316L wear; and albumin, concentration of 1g.L -1 , does not play a significant role in total 316Lwear. At cathodic applied potential E = -400 mV(SCE), a threshold concentration of 10 -1 mol.L -1 (NaCl solution), C th , indicates two behaviours: a protective effect below C th , and an additional anodic dissolution above C th . One might suggest that, beyond C th , the passive layer is not efficient for protecting against the corrosion. At this potential, albumin reduces wear due to corrosion and amplifies mechanical wear induced by corrosion. Albumin seems to act as an anodic inhibitor. To determine the mechanisms of synergism, a "more cathodic" potential is applied, E = -800 mV(SCE), during fretting-corrosion experiments.Consequently, the corrosive wear can be neglected and the mechanical wear can be only measured.

High-Cr white cast irons (WCIs) are multiphase alloys commonly used in aqueous industrial environments in applications that require both high abrasion and high corrosion resistance. Various electrochemical techniques can be useful in elucidating tribocorrosion characteristics of metallic materials undergoing wear in a corrosive environment. This study is focused on the interpretation of electrochemical measurements applied to three-body abrasion corrosion contacts of high-Cr WCIs. Particular attention has been paid to determine whether tribo-electrochemical data can pick up any effects that the multiphase microstructure of WCIs may have on the tribocorrosion characteristics, especially in environments containing chloride ions. Since both wear and corrosion of multiphase alloys are usually not uniform, their tribocorrosion behaviour is difficult to study and is still poorly understood. The experimental results are discussed in terms of benefits and limitations of tribo-electrochemical techniques such as polarization (potentiostatic, potentiodynamic) and electrochemical noise (galvanic coupling, potentiostatic) in studying abrasion corrosion behaviour of high-Cr WCIs. The application of high-resolution surface analysis techniques (microprobe, NanoSIMS, C-AFM and SKPFM), used in support of the electrochemical data interpretation, is also demonstrated.

“…Thus the friction under small displacements, i.e. the fretting corrosion (Barril, 2002;Bethune, 1968;Eden, 1911;Geringer, 2005;Geringer, 2006;McDowell, 1953;Tomlinson, 1927;Tomlinson, 1939;Uhlig, 1954;Waterhouse, 1955;Waterhouse, 1980), could occur. One will not pay attention on this point in this work.…”
