“…For NbC–CC, repetitive fracture and generation of the oxide film are responsible for the higher wear rate. Increased the addition of ceramic particles was mentioned in [25] as a way to improve wear resistance, but this also reduces its toughness. In contrast, the oxide film of ZrO 2 formed in situ by ZrC–CC not only prevented further oxidation of the coating but also improved the wear resistance due to the ceramic transformation of the oxide protective film.…”

“…The development of such composite coatings provides protection against localized heating or oxidation, friction, and wear, corrosion, etc. [24,25], thus improving the performance of the parts and making industrial costs lower. ZrC and NbC belong to the group IV transition metal carbides, which are characterized by a melting point well above 3400°C and are often used as a reinforcing phase at high temperatures [17,18].…”

Nowadays, studies of high entropy alloys (HEAs) have shown excellent properties. To improve the high-temperature wear resistance of CrMnFeCoNi alloy, refractory carbides (NbC and ZrC, respectively) reinforced CrMnFeCoNi composite coating were prepared by laser cladding (LC), and its wear performance was investigated. The composite coating showed no cracks or other defects that had metallurgical bonding with the substrate. Those coatings exhibited oxidative and adhesive wear mechanisms in reciprocating wear tests at 600°C. In contrast to the strengthening of NbC, the ZrC in the coating rapidly oxidized during high-temperature wear, forming a large amount of ZrO 2 . These oxides formed in wear promote the formation of a protective film, further improving the oxidation resistance and wear resistance of the coating.

“…Although the introduction of a ceramic phase could improve the wear‐resistance of a coating, there were differences in the ability to improve the wear‐resistance. Da et al [ 80 ] prepared three composite coatings of CrMnFeCoNi‐TiC, CrMnFeCoNi‐NbC, and CrMnFeCoNi‐B 4 C on a 304 stainless steel substrate. They found that the best wear‐resistance was obtained for the B 4 C coating, followed by the TiC coating.…”

With the continuous development of the aviation and aerospace industries, there is an increasing demand for surface coatings that can enhance the wear‐resistance and lubricity of substrates. High‐entropy alloy (HEA) coatings and high‐entropy alloy‐based composite coatings (including ceramic and lubricating phases) have attracted large attention, which is due to their excellent properties. They have, therefore, developed rapidly in the past decade. This article reviews the current status of research on the tribological properties of the HEA coatings and HEA‐based composite coatings that have been prepared by laser cladding technology. The focus is then on the wear‐resistance and wear‐reduction mechanism of the coatings. Furthermore, the review analyzes the influence of element addition, atomic ratio change, and process parameters on the coating organization and properties. The problems that have to be solved in the development of tribology‐based HEAs coatings, and the expected future development of HEA the coatings, are also discussed.

“…Up to now, many CoCrFeNi-M HEACs with excellent properties were explored, where M might be the following elements such as Al, B, Cu, Ti, Si, Mo and V [7][8][9][10][11][12][13][14][15][16][17][18][19][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Especially, elements with large atomic radius, such as Ti, Mo and V, have noteworthy strengthening effects on the coating.…”

“…The AlCoCrFeNiMo x coating showed a maximum hardness value of 706HV 0.2 , which was about 3.5 times that of the substrate (about 200HV 0.2 ), and the coating exhibited improved wear resistance compared with the substrate [29]. Furthermore, ceramic-reinforced CoCrFeMnNi HEA composite coatings were prepared on the surface of H13 steel, the coatings exhibited low hardness, low wear rate and high coefficient of friction [32,33].…”

Laser-cladding CoCrFeMoNi high-entropy alloy coating is composed of face-centred cubic, σ and µ phases. After annealing at 700 °C, many needle-like precipitates of the σ phase are found in the FCC solid solution, and the granular µ phase precipitated at the edge of the primary net-structural σ phase. After annealing at 800 °C, granular µ phases are found inside the primary σ phase. The friction coefficients of the coatings (as-cladded, as-annealed at 700 °C and 800 °C) decrease dramatically compared with the substrate of H13 steel. Obvious spheroidising of the σ phase at 900 °C leads to a decrease of hardness and an increase of friction coefficient. Furthermore, the CoCrFeMoNi high-entropy coatings show better corrosion resistance than H13 steel in 3.5 wt-% NaCl solution.
