Biotribocorrosion—an appraisal of the time dependence of wear and corrosion interactions: I. The role of corrosion

Abstract

With the increasing interest in metal-on-metal (MoM) joint implants, studies have been focused on their wear and corrosion behaviour. Integrated electrochemical tests have been conducted and are reported in this paper. The corrosion, wear and wear–corrosion behaviour for three materials (high carbon CoCrMo, low carbon CoCrMo and UNS S31603) have been discussed. Corrosion effects on the overall performance for the three materials are analysed. Two distinct regimes have been found for the three materials: (a) the running-in regime and (b) the steady state regime, in line with other research. Even in the steady state regime, 20%–30% of the material degradation can be attributed to corrosion-related damage. High carbon CoCrMo showed excellent corrosion, wear and corrosion–wear resistance and therefore it delivered the best overall performance in terms of a lower wear rate, a lower friction coefficient and a higher resistance to corrosion.

Tribo-corrosion of coatings: a review

“…The fretting corrosion behaviour of a Ti6Al4V alloy in contact with an alumina ball has been investigated by Barril et al [10] in a 0.9% sodium chloride solution. The tests were carried out using a fretting test rig equipped with an [11]. Corrosion effects on the overall performance for the three materials are analysed.…”

Wear and Corrosion Interactions on Titanium in Oral Environment: Literature Review

“…Medical devices and apparatus are also vulnerable to wear and corrosion phenomena, as reported in literature [3][4][5][6]. Most often, there is a loss of material that can lead to the deterioration of the performance of that device, machine, or installation [1].…”

“…Nowadays, the tribocorrosion behavior of materials has been studied in biological environments originating the new designation of bio-tribocorrosion [3,[12][13][14][15]. Even though it is not possible to simulate the complex oral environment for biotribocorrosion tests, in vitro studies can, at least, determine the influence of each component on bio-tribocorrosion behavior of biomaterials.…”

“…Mechanical aspects such as applied forces, contact geometry, and type (sliding, fretting, rolling, or impact) determine the tribocorrosion rate for a given material [1][2][3][4][5]. Concerning contacting surfaces, the topography (e.g., roughness, adsorbed molecules, and oxide film properties), chemical composition, and microstructure (e.g., phase distribution, grain size, etc.)…”

“…Concerning contacting surfaces, the topography (e.g., roughness, adsorbed molecules, and oxide film properties), chemical composition, and microstructure (e.g., phase distribution, grain size, etc.) of materials play an important role in the tribocorrosion system [1][2][3][4][5]. Finally, the corrosion of a material depends on the chemical composition, pH, temperature, and presence of oxidative species in a gaseous or liquid environment [1].…”
