“…The ASTM G119 standard has been widely used to quantify the synergism of a large number of materials in different environments [33,34,[109][110][111][112][113][114][115][116][117]. Neville and Hu (2001) [118] performed erosion-corrosion tests and observed that the resistance to material loss did not increase with the increase in hardness of the studied alloy, since corrosion was found to have an important synergistic effect on erosion.…”

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.

“…It has been widely examined that a large volume fraction of martensite renders a galvanic effect between austenite and martensite phases, which causes a cathodic shift in E corr and thus decreases the corrosion resistance significantly [ 34 , 35 , 42 , 43 ]. Dislocations and other defects with high-distortion energy can reduce the electron work function and the energy barrier for electrochemical reactions [ 44 ]. High-density defects, therefore, can provide more active sites to increase the corrosion rate [ 45 ].…”

“…Under the corrosive circumstance, the recrystallized nanocrystalline materials with dense grain boundary but low distortion is favored by the diffusion of Cr, which provides more nucleation sites and adhesion work to form compact passive film [ 1 , 32 ]. On the other hand, recrystallization reduces the dislocation density and martensite content in surface layers, which improves the corrosion resistance by reducing the active sites and increasing the energy barrier of electrochemical reaction [ 44 , 45 ]. These are the reasons why corrosion resistance recovered dramatically after short-time annealing, and the SA 10s gradient sample achieved a moderate corrosion resistance ( Figure 6 ).…”

Martensite transformation and grain refinement can make austenitic stainless steel stronger, but this comes at a dramatic loss of both ductility and corrosion resistance. Here we report a novel gradient structure in 301 stainless steel sheets, which enables an unprecedented combination of high strength, improved ductility and good corrosion resistance. After producing inter-layer microstructure gradient by surface mechanical attrition treatment, the sheet was annealed at high temperature for a short duration, during which partial reverse transformation occurred to form recrystallized austenitic nano-grains in the surface layer, i.e., introducing extra intra-layer heterogeneity. Such 3D microstructure heterogeneity activates inter-layer and inter-phase interactions during deformation, thereby producing back stress for high yield strength and hetero-deformation induced (HDI) hardening for high ductility. Importantly, the recrystallized austenitic nano-grains significantly ameliorates the corrosion resistance. These findings suggest an effective route for evading the strength–ductility and strength–corrosion tradeoffs in stainless steels simultaneously.

“…In many cases, the wear rate in solutions was usually larger than that due to dry wear [8,9]. Because of the combined action of mechanical and electrochemical mechanism, the material loss due to synergistic effect of wear-corrosion often exceeds the sum of the separate corrosion and wear loss.…”
