These decorative coatings require, not only an attractive appearance for market applications, but also an ability to protect the surface underneath. Because of this, corrosion, wear and their combined effects (termed tribo-corrosion) are particularly important for lifetime prediction.The tribo-corrosion behaviour of a range of single layered titanium oxycarbide, TiC x O y ,coatings, produced by DC reactive magnetron sputtering, has been studied and reported as a function of electrode potential (-0.9 V, -0.5 V, 0.0 V and +0.5 V) and applied load (3, 6 and 9 N). The study was conducted in a reciprocating sliding tribosystem (Plint TE 67/E) in a bio fluid (an artificial perspiration solution) at room temperature. During the wear tests, both the open-circuit potential and the corrosion current were monitored. 2The results showed that electrode potential and load have a significant influence on the total material loss. The variations in R p (polarization resistance) and C f (capacitance) before and after sliding, obtained by Electrochemical Impedance Spectroscopy (EIS)were evaluated in order to provide an understanding of the resistance of the film in such conditions. Tribo-corrosion maps were generated, based on the results, indicating the change in mechanisms of the tribological and corrosion parameters for such coatings.

Assessing the corrosion-wear behaviours of Hastelloy C276 alloy in seawater

“…Over past few years, investigations on tribocorrosion of materials subjected to corrosion and wear are a research hot spot. Efforts have been made to identify the synergistic effect between corrosion and wear and quantify the synergistic components by mathematical model . Most studies have found that synergistic effect between corrosion and wear leads to total material loss far more than the sum of wear and corrosion alone .…”

The Role of Nicotine in the Corrosive Behavior of a Ti‐6Al‐4V Dental Implant

“…Although one previous study suggested that both Ti alloy and CpTi have similar basic corrosive behavior, a future study is needed to test the response of CpTi when exposed to similar conditions. In addition, further studies are required to examine the degradation properties of the implant surface under simultaneous mechanical and electrochemical influence (known as tribocorrosion) …”

“…In addition, further studies are required to examine the degradation properties of the implant surface under simultaneous mechanical and electrochemical influence (known as tribocorrosion). 49,50 This study can also be extended to understand the cellular response of osteoblast cells to corroded surfaces resulting from nicotine consumption. Reporting specific chemical reactions and subsequent corrosion kinetics are beyond the scope of the current article due to limitations in the testing methods; however, they will be considered in future work.…”

Response of duplex Cr(N)/S and Cr(C)/S coatings on 316L stainless steel to tribocorrosion in 0.89% NaCl solution under plastic contact conditions

“…Indeed, many efforts have been made to improve the tribocorrosion performance of biodemical alloys by surface coatings, including diamond‐like carbon coatings, ion implantation, TiN and TiC based coatings, CrN based coatings and surface alloying . In particular, detailed studies have been performed on the potential of S‐phase coating and CrN coating to improve the tribocorrosion behavior of biomedical alloys .…”
