“…It is possible that fretting corrosion initiated crevice corrosion- 25,26 like behavior to cause the more severe corrosion damage seen in these retrievals, but the fact that corrosion damage was seen remote from the taper contact region disproves it in this case. Chemistry changes in the local solution from processes within the contact regions may result in these nontribological forms of corrosion and such fluid may egress from the crevice and induce similar corrosion processes in the adjacent alloy surfaces resulting in the discoloration and local pitting.…”

Corrosion of modular metal-on-metal acetabular tapers in total hip arthroplasty (THA) systems is often attributed to mechanically driven processes. Recent findings suggest that mechanically assisted crevice corrosion (MACC) might not be the dominant cause of corrosion in shell-liner tapers. This study aims to document and present the corrosion modes observed in metal-metal acetabular liners. Twenty-one retrieved wrought CoCrMo liners were examined using digital optical microscopy (DOM), scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS). Corrosion-related damage was documented in nonengagement taper regions, outside of direct taper contact. Within engagement regions, nonmechanically driven corrosion features (pitting, intergranular corrosion) were observed adjacent to fretting and material transfer, which rely on mechanical contact; corrosion independent of MACC was observed even in contact regions. Corrosion types observed included intergranular corrosion (IGC), pitting attack, phase boundary dissolution, all both outside and inside of taper junctions, and MACC within contact regions of the taper. Typical fretting scars associated with MACC were mostly absent, and were not always associated with corrosion damage where present. Finally, hard phase particles (Mo-Si-O) released from the wrought CoCrMo microstructure had redeposited within regions with material loss. Acetabular taper corrosion modes differ significantly from those in head-neck tapers and are dominated by electrochemically driven processes, not mechanical processes, as indicated by corrosion in noncontact regions. With greater prevalence of dual mobility hip implants, acetabular taper corrosion processes must be understood in order to limit their impact on device performance.

“…MACC consists of the conjoint effects of surface disruption of oxide films on passive alloy surfaces of titanium (Ti), cobalt‐chromium‐molybdenum (CoCrMo), and stainless‐steel alloys (316L SS), and the electrochemical responses associated with surface oxide disruption. The process of fretting crevice corrosion in modular tapers (a particular form of MACC) has raised concerns related to release of corrosion and wear debris and metal cations, and the local tissue reactions that may arise (Cooper et al, 2012; Gilbert, Buckley, & Jacobs, 1993; Goldberg, Gilbert, & Jacobs, 2002; Liu, Zhu, Pierre, & Gilbert, 2019; Urban, Jacobs, Gilbert, & Galante, 1994).…”

Mechanically assisted crevice corrosion may disrupt passive oxide films on medical alloys and lead to rapid repassivation reactions which generate corrosion currents and shifts in electrode potential due to the non-equilibrium nature of the reactions and the transient unbalancing of anodic and cathodic reactions. This study presents a theoretical approach to predict currents and voltages over time utilizing the concepts of heredity integrals, area-dependent surface impedance, contact mechanics and the high field physics of oxide repassivation. Two heredity integrals are presented relating, first, the sliding mechanics and oxide film repassivation physics to the current, and second, relating the electrode potential to the current using impedance concepts. Current-potential-time responses to controlled fretting conditions were measured across a fretting frequency from 0.2 to 10 Hz and compared to theoretical results. The coupled integrals were shown to predict the overall current-potential-time behavior for CoCrMo alloy surfaces under several controlled fretting corrosion conditions (loads, sliding speeds, etc.) with a high degree of similarity. These models can be adapted to numerical analyses of tribocorrosion to predict performance.

“…Neither use samples with geometry representative of prostheses, which has been identified as important to performance clinically. 8 Although local crevice corrosion effects have been observed around fretting damage in pin-on-disc electrochemical studies, 73 neither potentiodynamic or EIS studies reproduce the crevice geometry critical to the MACC phenomenon. A pin-on-disc or similar test apparatus allows particles generated during a frettingcorrosion simulation to escape the region of interest.…”

In vitro test methods are challenged by the multi-factorial nature of head-neck taper connection tribocorrosion due to the consequences of simplification. Incorrect study design and misinterpretation of results has led to contradictory findings regarding important factors affecting head-neck taper tribocorrosion. This review seeks to highlight important considerations when developing in vitro test methods, to help researchers strengthen their study design and analyze the implications of others’ design decisions. The advantages, disadvantages, limitations and procedural considerations for finite element analyses, electrochemical studies and in vitro simulations related to head-neck taper connection tribocorrosion are discussed. Finite element analysis offers an efficient method for studying large ranges of mechanical parameters. However, they are limited by neglecting electrochemical, biological and fluid flow factors. Electrochemical studies may be preferred if these factors are considered important. Care must be taken in interpreting data from electrochemical studies, particularly when different materials are compared. Differences in material valence and toxicity affect clinical translation of electrochemical studies’ results. At their most complex, electrochemical studies attempt to simulate all aspects of headneck taper connection tribocorrosion in a bench top study. Effective execution requires in-depth knowledge of the tribocorrosion phenomenon, the involved mechanisms, and their measures such that each study design decision is fully informed.
