“…Based on results presented in the literature [5,13], the degree of wear is expected to increase from D p ¼ 0, x ¼ 0 to a maximum value x max following an S-shaped curve. The value of this maximum degree of wear varies for each specimen.…”

“…Jiang and Arnell [13] tried to solve some of these problems by including a gradual increase of x in the wedge formation regime based on a low cycle fatigue mechanism. However, the physical interpretation of such a mechanism is unclear as the model is applied to single pass scratching and hence the fatigue life of the surface in contact is set to 1 cycle.…”

“…This factor is introduced because the material displaced from the wear groove by the sliding of a hard particle may not be completely removed in a single wear event [92][93][94][95][96]. In the case of erosion, the material removal factor can be related directly to the deformation wear factor as proposed by Bitter [90,91] which is defined as energy needed to remove a unit volume of material from the body surface by deformation wear.…”

Wear by hard particles can involve abrasion or erosion and is one of the most severe forms of wear. When a corrosive environment is present, the material loss rate can be significantly increased due to interactions (synergy) between the mechanical and chemical/electrochemical actions. In developing strategies for mitigating such adverse synergistic effect, it is important to understand the complex effect of various parameters on material loss under given tribocorrosion conditions. In this paper, a model is presented for wear-corrosion synergy in abrasive wear by hard particles applicable to many conditions in both the marine renewable (abrasion by high concentrations of large sand particles on tidal turbines) and extractive metallurgy (abrasive wear in mineral extraction). The mechanical wear loss is modeled based on the grooving mechanism (micro-cutting/micro-ploughing). Wear-enhanced corrosion is calculated from the fresh surface areas generated by grooving and the corresponding transient corrosion current. The concept of “corrosion-degraded layer” on the worn surface is introduced to account for the corrosion-enhanced wear; within this corrosion-degraded layer, the material loss rate is higher under the same mechanical wear conditions than in the material that is unaffected by corrosion. Based on the model, the effect of wear conditions on synergy in hard particle wear-corrosion has been discussed. The relative thickness of the corrosion-degraded layer to the depth of hard particle penetration (grooving) in the mechanical wear is found to be an important parameter in determining the relative severity of synergy in different tribo-corrosion systems. Good qualitative agreement has been observed between the predictions and published experimental results obtained from a range of abrasion-corrosion and erosion-corrosion lab testing.

“…The relation between D p and ξ is studied by Kayaba et al [13] who distinguished three wear modes; ploughing, wedge formation and cutting, each with a corresponding characteristic value of ξ (0.0, 0.50 and 0.875, respectively). Based on the experimental work of Kayaba et al, Jiang and Arnell [16] derived a relation for ξ in the wedge formation regime based on a low-cycle fatigue wear mechanism. Because ξ depends on many variables, see e.g.…”
