“…The data of corrosion resistance of the boride coatings were mostly presented in the literature using modeling conditions when the coated steel samples were tested in some acidic or salty media by immersion and potentiodynamic polarization experiments and electrochemical impedance spectroscopy . However, these testing methods do not correspond to real application conditions, and they may indicate only a very generic corrosion behavior of the studied materials.…”

“…However, because the Fe‐B and Fe 2 B phases have some difference in their morphology and thermal expansion, the boronizing mix composition and technology should be optimized to minimize the micro‐crack formation between these phases. According to some papers, boronized coatings perform well in different corrosive environments. However, the studies devoted to corrosion resistance of the boronized coatings obtained through thermal diffusion are rather limited, especially for their use in the corrosive environments of mineral processing, refinery, and power generation.…”

The corrosion related issues in oil production can be significantly reduced using the coatings based on the compounds from the metals of the IVb-VIb and VIII groups and the non-metallic elements of the IIIa-Va groups with strong covalent bonds and high thermodynamic potentials. Iron boride-based coatings with consolidated structures are successfully applied through the thermal diffusion process to protect large production components from steels and ferrous alloys. The principles of the thermal diffusion coating formation are reported. The Fe-B-based coatings successfully withstand high temperaturehigh pressure water steam contained H 2 S, CO þ CO 2 , hydrocarbons, chlorides in simulating oil field conditions tested in the autoclave and in the pressurized Atlas cell, and in strong acidic environments.

“…The experiments with the BN-based coating preparation have been conducted using inexpensive carbon steels (chemical composition, wt-%, as C 0.15-0.20, Si 0.20-0.23, Mn 0.60-0.75, Cu 0.30-0.35, Ni 0.10-0.15, Cr 0.10-0.16, Mo 0.02-0.05 and Fe as a balance) or boronised carbon steels as the substrates. Boronised coatings are widely used for the wear-and corrosionprotection of steels in a variety of applications [40][41][42][45][46][47][48][49][50][51][52]. The boronised steel samples (the mentioned above carbon steel was used as the substrate for boronising) were prepared according to the established at Endurance Technologies Inc. (ETI) thermal diffusion process [50][51][52].…”

Preparation of boron nitride (BN)-based coatings for friction and corrosion conditions has been proposed and made through the thermal diffusion process following chemical vapour deposition principles. It includes the formation of gaseous B-and N-based species due to high-temperature reactions (decomposition) in the B-and N-rich powders with consequent deposition of B and N onto the heated substrate and their diffusion into the substrate with formation and consolidation of a thin BN layer. The proposed process can be used for complex-shape components employing simple production equipment.

“…Some reliable coatings are inapplicable for protection of the inner surface of long tubing and complex shape components. In contrast, the thermal diffusion surface engineering technology, specifically boronizing and aluminizing of steels, can be used to protect critical components, including long tubing, exposed to harsh corrosion conditions [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Recently, advanced coating materials obtained through the thermal diffusion process were considered and tested, for the first time, for high-temperature sulfidation applications with promising results after exposure in H 2 S-Ar flows at 500 °C [ 39 ].…”

The high-temperature sulfidation-oxidation corrosion resistance of protective coatings deposited on carbon and 316L steels was studied. The coatings obtained via the thermal diffusion process had multi-layered architectures and consisted of aluminides, iron borides, or iron boride–TiO2 layers. The protective coatings experienced a minimal rate of mass changes, insignificant scale formation, and no delamination and surface micro-cracking after 504 h of exposure in 1% (Vol.) H2S-air atmosphere at 500 °C. Furthermore, the coatings demonstrated a high degree of integrity compared to bare 316L stainless steel. Aluminized steels demonstrated the highest performance among the studied materials. The developed thermal diffusion coatings are promising candidates due to their enhanced stability in H2S–air atmosphere; they may be employed for protection of inner and outer surfaces of long tubing and complex shape components.
