“…The obtained coating exhibits excellent resistance to wear, corrosion and high temperature oxidation over a wide range of temperature [4]. Conventional Ni60 coatings were often prepared by the following deposition technologies: flame spraying, high-velocity oxygen fuel spraying (HVOF), electric arc spraying, plasma spraying, plasma-transferred arc welding, and laser cladding (LC) [5,6]. In thermal spray process, plasma jets, electric arc or high-velocity oxygen fuel are used to melt or partially melt the particles and also to accelerate the powder to impact on the substrate.…”

“…Thermally sprayed Ni-based self-fluxing alloy coatings are exposed to different conditions in exploitation. That is why they are explored from nearly all aspects, i.e., investigations are aimed at those coatings’ resistance to different types of wear and to corrosion [ 3 ], but the influence of external mechanical loads, residual stresses, as well as microstructures, have also been investigated [ 16 ]. While investigating, many authors employed a scientific approach to designing the experiment.…”

In investigating thermally sprayed Ni-based self-fluxing alloy coatings, widely applied under conditions of wear, corrosion, and high temperatures, designed experiments and statistical methods as a basis for modeling and optimization have become an important tool in making valid and comparable conclusions. Therefore, this paper gives an overview of investigating Ni-based self-fluxing alloy coatings deposited by thermal spraying by the use of designed experiments and statistical methods. The investigation includes the period of the last two decades and covers the treatments of flame spraying, high-velocity oxy/air fuel spraying, plasma spraying, plasma-transferred arc welding, and laser cladding. The main aim was to separate input variables, as well as measured responses, and to point out the importance of correct application of statistical design of experiment. After the review of the papers, it was concluded that investigators have used the process knowledge to analyze and interpret the results of the statistical analysis of experimental data, which is in fact the best way of using the design of experiment in every research. Nevertheless, more attention should be given to correct planning and conducting the experiments to derive the models suitable for the prediction of measured response and which could be an appropriate input for single- or multi-objective optimization.

“…As a conventional coating material with high hardness, sufficient strength, excellent wear, and heat resistances, Ni-based self-fluxing alloy has been widely used in fields of petroleum and chemical industries, power, and national defense [17,18]. By now, a large number of coating technologies, such as overlay welding, laser cladding, flame spraying, high velocity oxy-fuel spraying, and plasma spraying have been employed to deposit Ni-based self-fluxing alloy coatings [17][18][19]. In addition to the high hardness and excellent wear resistance at both room temperature and high temperature, good toughness makes Ni-based self-fluxing alloy a more appropriate reinforcement than the brittle traditional ones.…”

In this comparative study, Ni60 was used as a reinforcement and added into an AlCoCrFeNiTi high-entropy alloy (HEA) matrix coating in order to enhance its hardness and wear resistance. An AlCoCrFeNiTi/Ni60 coating was prepared by plasma spraying with mechanically-blended AlCoCrFeNiTi/Ni60 powder. The coating microstructure was observed and analyzed. Bonding strength, microhardness, and wear resistance of the coating were investigated. The results showed that a compact AlCoCrFeNiTi/Ni60 coating with Ni60 splats uniformly distributed in the AlCoCrFeNiTi matrix was deposited. After spraying, matrix body-centered cubic (BCC), face-centered cubic, and ordered BCC phases were detected in the coating. The added large Ni60 particles played an important role in strengthening the coating. Tensile test results showed that bonding strength of this coating was above 60.1 MPa, which is far higher than that of the AlCoCrFeNiTi HEA coating in the previous study. An average microhardness of 676 HV was obtained for the main body of the coating, which is much higher than that of the AlCoCrFeNiTi HEA coating. Solution hardening in γ-Ni and dispersion strengthening of the hard interstitial compounds, such as Cr 7 C 3 , CrB, Cr 2 B, and Cr 23 C 6 increased the hardness of Ni60, and then the AlCoCrFeNiTi/Ni60 coating. During wear testing at 25 • C, adhesive wear and abrasive wear occurred, while, at 500 • C, abrasive wear took place. Volume wear rates of the coating at 25 • C and 500 • C were 0.55 ± 0.06 × 10 −4 mm 3 •N −1 •m −1 and 0.66 ± 0.02 × 10 −4 mm 3 •N −1 •m −1 , respectively. Wear resistance of this coating was better than that of the AlCoCrFeNiTi HEA coating, which can be attributed to addition of the hard Ni60. Therefore, Ni60 is an appropriate reinforcement to further enhance the wear resistance of HEA coating.
