“…Figure 3 displays the patterns of samples with different content of nickel; the strong peaks (110), ( 200), ( 211) and (220) planes are found in all samples. Based on the standard a-ion, Cr and Ni pattern, the Fe-Cr solid solution was deduced in the sample without nickel, but the Fe-Cr-Ni solid solution with a body-centered cubic (BCC) crystal structure could be inferred in the specimens with nickel (Prakash and Nath, 2018). Combined with the microstructures in Figure 2, it could be deduced that the BCC ferrite and body-centered tetragonal troostite presented in the specimens with nickel (Kishor et al, 2018).…”

Purpose This paper aims to search the optimum content of Ni on the microstructure, phase and electrochemical behavior of high-strength low alloy (HSLA) steel in the 3.5 wt.% NaCl solution. Design/methodology/approach The microstructure and corrosion resistance of Ni-containing HSLA steel in the simulated marine environment was studied by optical microscopy, scanning electron microscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electrochemical techniques. Findings The sample containing 3.55 wt.% of nickel exhibited a finer grain size of 10 μm and a lower icorr of 2.169 µA cm−2. The XRD patterns showed that the Fe-Cr-Ni solid solution, FeC and Cr3C2 were observed in samples when Ni was added. Besides, the 3.55 wt.% of nickel addition enhanced the charge transfer resistance of the low alloy steel which suggested the sample possessed excellent inhibition of electrochemical reaction and corrosion resistance. The XPS spectrum suggested that nickel was beneficial to improve the corrosion resistance of steel by forming protective oxides, and the ratio of Fe2+/Fe3+ in protective oxides was increased. Practical implications Finding the comprehensive performance of HSLA steel which can be applied to unmanned surface vehicles in marine operations. Originality/value This study has a guiding significance for optimizing the composition of HSLA steel in a Cl- containing environment.

“…They conducted annealing at different temperatures and found decrease in wear loss due to influence on the microstructure with the increased depth of work-hardening layer. 1 Prakash and Nath 15 performed heat treatment at 1050 °C of 13/4 MSS followed by oil quenching and tempering at 600 °C. After accomplishment of low-temperature salt bath nitriding, they found the steel sample nitrided at 450 °C to have higher SE resistance due to expanded martensitic structure and the sample nitrided at 500 °C to exhibit higher erosion due to development of brittle microstructure of CrN phase compared to heat-treated and tempered steel.…”

Slurry erosion usually results in the form of damage to the materials of different components having underwater working domain. Numerous industries have suffered due to this kind of wear resulting in frequent breakdowns demanding repeated financial assistance and poor productivity. Properties and tribo-performance of materials related to distinct slurry applications play a significant role in arresting the slurry erosion wear. Slurry erosion depends on different parameters such as impact velocity, impingement angle, shape and size of erodent, slurry concentration and so on. These parameters differ from one application to another and accordingly, specific materials are selected knowing the extent and severity of slurry erosion wear. In the last decade, many authors studied parametrically the tribo-slurry erosion performance of materials, few of them correlated their investigations to the actual in situ conditions of applications. Various authors have analyzed the effect of operating parameters on the mechanism of erosion and conducted the comparative studies of different materials. Many of the investigators attempted to improve the properties and tribo-slurry erosion performance of materials through surface modification techniques; coating, reinforcement, heat treatment, thermo-mechanical process etc. This review is an effort to covers all such kind of explorations.

“…However, the relatively low chromium con-tent (~13 wt.%) in solutions containing chlorine results in lower corrosion resistance than other stainless steels [5]. Some surface modification methods to raise the corrosion resistance of 2Cr13 steels have been applied, including nitriding, nitrocarburizing, laser transformation hardening, plasma immersion ion implantation, physical vapor deposition, and the other processing technologies [6][7][8][9][10][11][12][13][14][15].…”

The influence of electric potentials on the characteristics of modified layers with plasma nitriding of 2Cr13 stainless steel at a high temperature was investigated. Three active screens were placed on the cathodic plate. Three groups of 2Cr13 stainless steel samples were set with cathodic, anodic, and floating potentials. Samples were nitrided at 500 °C for 5 h in an ammonia atmosphere. The treated samples were analyzed using x‐ray diffraction, scanning electron microscopy with energy dispersive x‐ray spectroscopy, surface roughness tester, and atomic force microscopy. It is proved that nitriding treatments can be suitably carried out at three electric potentials, but the corresponding modified layers take on different microstructure, morphology, and hardness behaviors. It found that the three nitrided samples are mainly composed of the ϵ−Fe2‐3N and γ’−Fe4N phases. The order of thicknesses of the nitrided layers is: floating < anodic < cathodic potential. The results also demonstrated that electric potentials play essential roles in the corrosion resistance and tribological properties in plasma nitriding treatment. Because there is no visible precipitation of chromium nitride in the modified layer, the corrosion resistance of the floating nitrided sample is better than that of the other two samples.
