“…The silicon element can be more soluble in the matrix globule than in the eutectic solid solution. In the previous literature, the microhardness of Ni-Si eutectic alloy first increases, then decreases with increasing Si/Ni ratio caused by the difference of melting temperature [9]. Boron can produce the small amount of boride compound in this situation [6].…”

Solid particle erosion on surface of material effects on life time for them such as the turbine brade, boiler tube and chemical processing equipments. Thermal spray is one of various technique which used for the repairing or building up new surface. The objective of this experiment is to study the influence of thermal spray Ni-Si-B coating parameters on the solid particle erosion resistance at room temperature. The coating parameters were the distances between coating nozzle and the substrate of 10, 15, and 20 mm and travel speeds of 1.0 and 1.5 mm s-1 respectively, leading to the difference of heat inputs. The hardness of coating surfaces was measured by Vickers hardness. The microstructure of coating surfaces was examined by using an optical microscope (OM) and scanning electron microscope (SEM). Moreover, solid particle erosion resistance of coating surfaces was investigated on the erosion test rig at room temperature. Erosion rates of specimens were assessed by the calculation of weight loss which measured using an electronic balance (0.1 mg resolution). The relationship between erosion resistance and hardness was studied coincide with the microstructure examination. According to the erosion resistance evaluation, it was found that an erosion rate of coating depended on the coating condition. Finally, wear scar morphology on the top of an eroded surface and cross-section area was observed by SEM. However, the coating parameters played an important role in the erosion resistance. The microstructure of coating concerned with coating parameters was further discussed with the erosion behavior in this research.

“…The appearance of the NiSi 2 alloy signal revealed that when the Si anode is directly formed against the NCM523 cathode, Ni cations may pass through the separator and get to the Si anode. 36,37 In this sense, the formation of the Ni-Si alloy is promoted from the cross-talk between the Si anode and the NCM523 cathode via the porous separator. During the cell formation, the dissolved Ni cations from the NCM523 cathode can nd their way to the Si anode and precipitate on the Si surface.…”

“…Due to the fact that not only pure metals, but corresponding ferroalloys, will be used for the smelting of experimental alloys in this study, as well as simpler smelting conditions, it is more appropriate to call the obtained experimental alloys quasi-high-entropy (CES) in the context of pseudo-high-entropy. Such terminology has already been used in other works [17,25].…”

This paper deals with the possibility of smelting quasi-high-entropy alloys (QHEAs) with the partial use of ferroalloys in the charge instead of pure metals. The Cantor alloy (CoCrFeMnNi) was used as the base alloy and the comparison sample, into which niobium was introduced in the amount of 14 to 18% by weight. The structure, hardness, strength, and tribological properties of prototypes were studied. The results obtained showed, on the one hand, the possibility of using ferroalloys as charge components in the smelting of QHEAs and, on the other hand, the positive effect of niobium in the amount of 14–17% on the strength and wear resistance of the alloy. Increasing the niobium content above 18% leads to its uneven distribution in the structure, consequently decreasing the strength and wear resistance of the alloy. The structure of the studied alloys is represented by a solid solution of FCC, which includes all metals, and the niobium content varies widely. In addition, the structure is represented by the phases of implementation: niobium carbide NbC 0.76–1.0, manganese carbide Mn7C3, and a CrNi intermetallic compound with a cubic lattice.
