“…Cao and coworkers developed [134] a predictive model considering the mechanical wear, wear-accelerated corrosion, and hydrodynamic lubrication applied to metal-on-metal implants. The model predictions were found to be consistent with tribocorrosion tests [135] and simulator results [136]. Recently, A.…”

This paper reviews the most recent available literature relating to the electrochemical techniques and test procedures employed to assess tribocorrosion behaviour of passive materials. Over the last few decades, interest in tribocorrosion studies has notably increased, and several electrochemical techniques have been adapted to be applied on tribocorrosion research. Until 2016, the only existing standard to study tribocorrosion and to determine the synergism between wear and corrosion was the ASTM G119. In 2016, the UNE 112086 standard was developed, based on a test protocol suggested by several authors to address the drawbacks of the ASTM G119 standard. Current knowledge on tribocorrosion has been acquired by combining different electrochemical techniques. This work compiles different test procedures and a combination of electrochemical techniques used by noteworthy researchers to assess tribocorrosion behaviour of passive materials. A brief insight is also provided into the electrochemical techniques and studies made by tribocorrosion researchers.

“…Note that the standard deviation leads to some difficulties to clearly detect the role of pH on the damage. In this region, the roughness of the two materials promotes an abrasive contact that enhances the degradation of the material [35,51]. Above 400 slidings, the wear surfaces increase linearly with time in agreement with the linear regime of wear.…”

“…Whatever the test, the volume of loss increases linearly with the sliding as predicted by the Archard's theory [3]. Even if this theory was initially developed for sliding in dry condition, it is often used in tribocorrosion until the mechanical contribution is significantly either than the chemical wear in the degradation mechanism [36,51]. In the Archard's law, the wear volume Vi (m 3 ) is proportional to the hardness of AISI430, H (Pa or kg.m -1 .s -2 ) and the normal load, F (N or kg.m -1 ).…”

“…Quantitative prediction of material loss from MoM bearing surfaces based on tribocorrosion concepts was firstly proposed by Mischler et al [6]. Cao et al [7–8] recently developed a comprehensive predictive model considering mechanical wear, wear accelerated corrosion and hydrodynamic lubrication that was able to predict with high precision the degradation of MoM implants in simulators. However, this model does not consider the build-up of tribomaterial as reported in [9–10].…”

In-situ generated tribomaterial in metal/metal contacts: Current understanding and future implications for implants

Artificial hip joints operate in aqueous biofluids that are highly reactive towards metallic surfaces. The reactivity at the metal interface is enhanced by mechanical interaction due to friction, which can change the near-surface structure of the metal and surface chemistry. There are now several reports in the literature about the in-situ generation of reaction films and tribo-metallurgical transformations on metal-on-metal hip joints. This paper summarizes current knowledge and provides a mechanistic interpretation of the surface chemical and metallurgical phenomena. Basic concepts of corrosion and wear are illustrated and used to interpret available literature on in-vitro and in-vivo studies of metal-on-metal hip joints. Based on this review, three forms of tribomaterial, characterized by different combinations of oxide films and organic layers, can be determined. It is shown that the generation of these tribofilms can be related to specific electrochemical and mechanical phenomena in the metal interface. It is suggested that the generation of this surface reaction layer constitutes a way to minimize (mechanical) wear of MoM hip implants.
