“…It is generally believed that the wear resistance of materials is closely related to hardness. [25,26] Solid solution strengthening and second phase strengthening can harden Stellite 21, so it can effectively improve the wear resistance of the coating. Moreover, carbide hard phases exist in the Stellite 21 coating, and when the coating surface contacts with the ZrO 2 grinding ball, these hard phases can effectively prevent the ball from continuous grinding and play a buffer role.…”

In this study, Stellite 21 Co‐based alloy coating was prepared on the surface of the H13 steel substrate by laser cladding. The phase composition, microstructure, chemical constitution, microhardness, and wear property of the coating were studied, respectively. The corrosion resistance of the coating was evaluated by electrochemical test and salt spray test. The results show that the coating is mainly composed of γ‐Co, CoCx, and Cr7C3 phases. γ‐Co solid solution matrix separates within the dendrites, while Mo‐rich intermetallic phases and carbides separate in the interdendritic regions. The average microhardness of the coating is twice that of the H13 substrate. The wear loss of the coating is 74.3% lower than that of the substrate, exhibiting better wear resistance. The main strengthening mechanisms of the coating are solid solution strengthening and second phase strengthening. The self‐corrosion potential of the coating is more positive than that of the H13 steel and the corrosion current density is only 1/160 of the H13 steel. The salt spray test after 168 h reveals that the coating exhibits much better corrosion resistance than that of the substrate.

“…In addition to the matching of wheels and rails, the lubrication conditions 11,12 and rail materials [13][14][15][16][17][18][19] also have a great influence on rail wear. Lu et al 12 reported that the average rail wear rates for the high rail gauge face and gauge corner were reduced by approximately 50% in the section where friction management was applied.…”

“…Konstantinova et al, 13 Ding et al 14 and Xu et al 15 used the plasma selective quenching technology to reduce rail wear, but this significantly increased wheel wear. 15 In Ref 16–19 it was found from laboratory that rail hardness or the ratio of wheel hardness to rail hardness has a significant effect on rail wear.…”

Two of the Shanghai metro lines suffered from severe side wear on the high rail, not only in sharp curves but also in large curves, and the service life of some rails on sharp curves was reduced by approximately 50% compared with the last rail replacement. Features and evolution rules for the rail side wear and the wheel flange wear were determined by field measurements and long-term monitoring. A rail wear prediction model, verified in our previous work, is used to reveal the influence of factors on rail wear. The results indicate that the poor lubrication condition at the rail gauge face is the main cause of severe side wear of the high rail, and the use of wheel profiles with low conicity and the loss of profile curvature of low rail profiles caused by the untimely maintenance also increase the side wear of the high rail. The service life of the high rail could be greatly extended by some countermeasures, such as repairing the worn shape of the low rail and repairing/improving the wayside lubrication system.

“…In the case of U71Mn rail steel, which is the alloy most frequently used for railway construction in China, researchers have focused on the mechanical properties of the welded joints [25,26] instead of the corrosion performance of the steel [27][28][29]. As U71Mn welded joints are subjected to the highest risk during service, and there is a need to investigate the variations in the weld grain size with the heterogeneous chemical compositions and microstructures [26].…”

The microstructural evolution and corrosion behaviour of railroad flash-butt-welded U71Mn joints and the effect of heat treatment were investigated via scanning electron microscopy and electrochemical measurements. The joint structures were found to mainly comprise pearlite and a few ferrites. The grains became finer and more homogeneous after heat treatment. Additionally, there was a decrease in the corrosion current density (1.71 × 10−5 A cm−2) and increases in the absolute corrosion potential (0.86 mV) and corrosion resistance (1088.83 Ω−1cm2). This was primarily attributed to the fewer Cl− ions at the homogeneous grain boundaries and fewer oxidation reactions on the joints after heat treatment. The findings of this study explain corrosion failure and will guide the development of corrosion-resistant joints for improved railroad quality.
