“…Owing to reduced cost in comparison with other metallic glasses, Fe-based metallic glasses are of particular interest for practical applications. Several attempts to deposit Fe-based metallic glass coatings by the thermal spraying methods have been made [12][13][14][15][16][17]. The formation of metallic glass coatings by thermal spraying is a challenge, as, during the deposition, conditions should be created either to preserve an amorphous structure of the material (in the case of spraying of amorphous alloy powders) or to produce amorphous layers through melting of the particles and rapid solidification.…”

“…Despite partial crystallization, the ability of the coatings to resist localized corrosion allowed the authors to recommend them as surface protection for marine environments. Xie et al [15] presented a comparative analysis of the microstructure and mechanical properties of Fe 48 Mo 14 Cr 15 Y 2 C 15 B 6 coatings obtained by detonation, plasma, and high-velocity oxygen fuel spraying. It was found that the detonation coatings possess the highest content of the amorphous phase among the studied coatings.…”

The present work was aimed to demonstrate the possibility of forming Fe66Cr10Nb5B19 metallic glass coatings by detonation spraying and analyze the coating formation process. A partially amorphous Fe66Cr10Nb5B19 powder with particles ranging from 45 µm to 74 µm in diameter was used to deposit coatings on stainless steel substrates. The deposition process was studied for different explosive charges (fractions of the barrel volume filled with an explosive mixture (C2H2 + 1.1O2)). As the explosive charge was increased from 35% to 55%, the content of the crystalline phase in the coatings, as determined from the X-ray diffraction patterns, decreased. Coatings formed at explosive charges of 55–70% contained as little as 1 wt.% of the crystalline phase. In these coatings, nanocrystals in a metallic glass matrix were only rarely found; their presence was confined to some inter-splat boundaries. The particle velocities and temperatures at the exit of the barrel were calculated using a previously developed model. The particle temperatures increased as the explosive charge was increased from 35% to 70%; the particle velocities passed through maxima. The coatings acquire an amorphous structure as the molten particles rapidly solidify on the substrate; cooling rates of the splats were estimated. The Fe66Cr10Nb5B19 metallic glass coatings obtained at explosive changes of 55–60% showed low porosity (0.5–2.5%), high hardness (715–1025 HV), and high bonding strength to the substrate (150 MPa).

“…Variation in particle size influences the corrosion properties of coating material. A decrease in spraying particle size increases the corrosion resistance of coating materials [8]. The best quality of spray can be obtained by optimising HVOF parameters such as particle velocity, powder feed rate, and spray distance, and in the response optimisation, the spray distance is indicated as the most significant factor affecting the spray/coating quality [9].…”

The high-velocity oxyfuel spraying (HVOF) method was used to coat Fe-Cr-Ti-based coating material Fe60Mo5C15Si10Cr0Ti10, Fe50Mo5C15Si10Cr10Ti10, Fe50Mo5C15Si10Cr10Ti0 on base material 316L stainless steel. A comparative analysis was performed to investigate the effect of alloying element chromium and titanium on corrosion and erosion properties of Fe-Cr-Ti coating material. NaCl solution (3.5 wt.) was used for the study of corrosion behaviour. The steady-state erosion wear was examined by varying parameters such as impact speed and impact angle. It was found that the micro-hardness and fracture toughness of Fe-Cr-Ti coating material with 10 wt-% titanium were 18.02 and 5.08% more than those of the coating material with 10 wt-% chromium, respectively. This showed that titanium played a more significant role than chromium in terms of mechanical and erosion properties and a less significant role in terms of corrosion behaviour. Fe50Mo5C15Si10Cr10Ti10 indicated the least wear and a smooth surface with very few pores and wear scars.

“…During the spraying process, oxidation of the sprayed powder should be avoided, as the oxide lms formed on the surface favor heterogeneous nucleation, and negatively affect the properties of the coatings [17][18][19][20][21][22]. Among thermal spraying methods, the impulse nature of detonation spraying allows the formation of wear resistant and dense coatings with low crystalline phase content [23]. The results of the investigation of the tribological and corrosion properties of Fe 51.33 Cr 14.9 Mo 25.67 Y 3.4 C 3.44 B 1.26 detonation coatings with high content of amorphous phase (content of crystalline phase 14.46 wt.%) and studying of wear mechanisms was presented in [24].…”

The Fe66Cr10Nb5B19 alloy coatings with high hardness (~ 850 HV300), low porosity (less 3%), low content of crystalline phase (less 2.5 wt.%), elevated nanohardness (average value 13.7 GPa), and high wear resistance were obtained in a wide range of detonation spraying modes. The results under dry linearly reciprocating sliding wear tests of coatings and stainless steel carried out according to ASTM G 133-05 are presented. The volume loss of detonation coatings obtained at an explosive charge of 50–70%, measured on an optical profilometer, is significantly lower than that of stainless steel. The similar values of volume scratches of Fe66Cr10Nb5B19 coatings obtained at an explosive charge of 40–70% can be attributed to similar values of porosity and content of crystalline phase. The scratch and spalling mechanisms are the main mechanisms of material removal from the coatings.
