“…At this level, lower wear rates were obtained compared to the single scratch values. The change in the wear rates pointed out the dominant effect of strain hardening in determining steels abrasion resistance [14]. Recent researches also proved that hardness is not the only parameter controlling wear resistance.…”

“…Moreover, the samples underwent work hardening during the grinding process, resulting in a slight increase in Vickers hardness, which was beneficial in preventing cavitation damage [ 34 ]. According to previous reports, work hardening occurs on the bottom and edges of scratches [ 35 ], resulting in martensitic transformation ( Figure 3 a) and grain refinement [ 36 , 37 , 38 ]. In samples with initial surface scratches, the higher hardness in the areas with scratches inhibited crack propagation when the cracks expanded to the scratches ( Figure 7 b and Figure 8 ).…”

Rough surfaces have been widely considered as negative factors affecting cavitation erosion resistance. However, this study presented the opposite result. Here, 316L stainless steel substrates and the arc-sprayed 316L stainless steel coatings were subjected to a specific grinding process that introduced scratches on the surfaces. The surface hardness values of these ground specimens were measured to evaluate the influence of the grinding-induced strain hardening. The cavitation erosion performance of the specimens was evaluated. The results showed that rough surfaces with scratches could enhance the cavitation erosion resistance, particularly at the early stage of cavitation erosion. The scratches had a greater effect on the cavitation erosion resistance of the coatings than on the substrates. Moreover, rough surfaces with initial surface scratches could extend the incubation period of the 316L stainless steel substrates due to the inhibition of the plastic deformation. The SEM observation showed that the scratch structure of the coating surface inhibited the growth of cracks and the propagation of cavitation pits. This study could also serve as a reference for investigating the cavitation erosion behaviors of materials with a particular surface feature.

“…Dual-indenter scratch tests can reveal the gouging resistance of a work-hardened surface by performing a small indenter scratch inside a large pre-scratched track. [19] This method has been proposed to rank materials based on their relative gouging abrasion resistance. Large work-hardened (WH) tracks were created by performing 15-mm-long scratches using the Bruker UMT Tribolab, fitted with a WC-Co ball with a 6.35 mm diameter.…”

Precipitation hardening is a promising approach for strengthening of Hadfield steels. The present study examines the potential to achieve this by combining vanadium addition (up to 2 wt pct) with short-time aging (15 minutes) at 1173 K (900 °C). It was found that such a treatment is sufficient to generate a dispersion of nanoscale precipitates that provided a significant increase in hardness. Small-angle neutron scattering and transmission electron microscopy measurements were performed to quantify the particle dispersion, and Orowan precipitate hardening predictions made using the parameters thus obtained show good correspondence with the observed rates of age hardening, suggesting the precipitates are resistant to shearing. The present steels containing vanadium showed a small reduction in work-hardening capacity and this is believed to be due to carbon depletion from the matrix. It is concluded that the addition of vanadium and a short aging treatment at 1173 K (900 °C) provide a promising pathway to imparting hardness increases that provide gouge resistance during the running-in period of components made from Hadfield steel. For optimum performance, additional carbon should be added to maintain the solute carbon content of the matrix, and hence the matrix work-hardening rate.
