“…Many publications have reported that HEA coatings demonstrate excellent corrosion resistance in aggressive environments. [32][33][34] In general, the factors affecting the corrosion resistance of HEA coatings include the passive film, alloy composition, and microstructure of the coating surface, which are closely associated with the composition design and preparation process parameters. Some published review articles summarized the reports on the properties, preparation technologies, and microstructure of HEA coatings.…”

For a long time, the corrosion problem of materials has been an essential factor in restricting high-tech and national economic development. As an effective means of corrosion protection, surface coatings have drawn extensive attention in the field of material corrosion. Performance improvement and a new composition system of high-entropy alloys (HEAs) have made HEA coatings a research hotspot. HEA coatings inherit the “four core effects” of bulk HEAs, especially high entropy and sluggish diffusion, making high-quality coatings exhibit outstanding corrosion resistance. At present, many reports have focused on the performance of HEA coatings in the field of severe corrosion environments. This article reviews the process parameters and different element contents on the corrosion resistance of HEA coatings in recent years. This paper describes the advantages and excellent corrosion resistance of HEA coatings, including the preparation methods and classification of HEA coatings. Moreover, exploration of the corrosion behavior and the mechanism of HEA coatings are described, and the influence of passivation behavior and microstructure change on the corrosion resistance of HEA coatings are discussed. Finally, the prospect of research on corrosion-resistant HEA coatings is proposed, and possible future research directions and ideas are suggested.

High-entropy alloys (HEAs) with high hardness are promising materials for advanced industrial manufacturing. In this study, the AlCrFeNiV HEA was designed and successfully prepared using a plasma instantaneous process. The hardness test showed that AlCrFeNiV had a high hardness of 1076 ± 15 HV, which was much higher than those reported in the literature. The microstructure of AlCrFeNiV was composed of two different types of body-centered cubic (BCC) structures, BCC1 (Al, Cr, Fe, and Ni) and BCC2 (enriched V and Cr). A mixture of different BCC systems produced solution strengthening, which was responsible for the superior hardness. Moreover, the reciprocating sliding wear behavior of HEA against Al2O3 balls under dry and lubricated conditions at ambient temperature was investigated. The wear rates of AlCrFeNiV against Al2O3 under dry wear and lubrication were 17.2 × 10−5 mm3 N−1·m−1 and 12.4 × 10−5 mm3N−1·m−1, respectively, which were of the same order of magnitude as the wear rates of BCC HEAs. Regardless of the dry wear or wear with lubrication, the wear mechanism of the HEA was abrasive and delamination wear.

“…Nowadays, among the nuclear power plants in the world, the most widely used is the fast neutron reactor. In fast reactors, liquid lead-bismuth eutectic alloy (LBE) has good thermo-physical properties, neutron economics and high chemical inertness, such that LBE has become one of several types of candidate material for coolants in fast neutron reactors [1][2][3][4][5]. LBE, however, at high temperatures has a strong corrosive effect on structural materials during the operation of the fast neutron reactor [6].…”

Corrosion Behavior of a Cr-Al Coating Deposited on 304 Austenitic Stainless Steel by Multi-Arc Ion Plating in Liquid Lead–Bismuth Eutectic

et al. 2022

In this paper, a Cr-Al coating was deposited using multi-arc ion plating (MAIP) on 304 austenitic stainless steel. The Cr-Al-coated sample was treated by vacuum annealing at 600 °C for 12 h, and its corrosion behaviors against static LBE were carefully evaluated by SEM, EDS and XPS at a temperature of 600 °C for 1000 h, compared with an uncoated sample. The results showed that the uncoated sample was corroded by the dissolution and oxidation of LBE severely; a duplex-layered oxide layer consisting of an outer Fe3O4 magnetite layer and an inner FeCr2O4 spinel layer was produced on the surface of 304 stainless steel after LBE corrosion. For Cr-Al diffusion coating, an oxide layer was formed that separated the LBE into the 304 matrix. XPS detection showed that the oxide layer primarily included Al2O3. Besides this, the hardness of the coating was tested with a Vickers hardness tester, and the annealed Cr-Al diffusion coating exhibited an average hardness of 260 HV, about five times as high as the Al coating before annealing, of which the average hardness was 48 HV.
