“…It is considered that materials such as 1.0037 (S235JR), 1.6523 (21NiCrMo2), 1.0503 (C45), 1.7225 (42CrMo4) steels, which are frequently used in machine industry and structural elements in the industry, can be used in the production of reactor components or control equipment when their chemical contents are taken into account. But the surface quality, corrosion resistance, machinability and weldability of steel materials are important in applications or usage because they can affect the physical properties of the materials [17,18]. However, the fact that the corrosion resistance of these materials is not as well as stainless steels constitutes a disadvantage [19].…”

In this study, S235JR (1.0037), 21NiCrMo2 (1.6523), C45 (1.0503), 42CrMo4 (1.7225) steels were coated with nickel, copper, silver, and tin. Then, the radiation shielding performances of the uncoated and coated steels were investigated. The steels were firstly designed by the coating processes via electrolytic plating method on behalf of Ni, Cu, Ag and Sn metals. The samples were then irradiated by radioactive sources for transmission of the gamma rays at photon energies in the range 81-383 keV photon energies to measure linear and mass attenuation coefficients (LAC-µ, MAC-µ/) of the pure and coated steels by Ni, Cu, Ag and Sn. Half and tenth value of layers (HVL and TVL) of investigated materials were then calculated at the same studied photon energies. The materials were compared with each other as well as with some shielding concretes in terms of mean free paths (MFP) wherever possible. The coated steels were found to be better shielding materials than the concretes due to lower MFP values they had, and they showed also better shielding than reference materials up to 35.31% relative difference in MFP. It was concluded that coating processes improved the shielding properties of the steels.

“…Carbon steel is widely used in different industries, including marine and nuclear energy. For example, it is used in the construction of reactor pressure vessels and piping in light water reactors and for load-bearing components in marine energy converters [1][2][3]. However, carbon steel is prone to corrosion in aqueous media.…”

Carbon steel is a widely used structural material; however, it lacks corrosion resistance in water environments. An alternative approach to overcome this challenge is to implement the deposition of inherently corrosion-resistant ceramic coatings. SiC/C/Al coatings were developed at 700°C, using polycarbosilane in combination with Al and C, which were included as active and passive fillers, respectively. This work shows that it is necessary to use Al particle sizes below 10 µm for them to function as an active filler below 900°C. Owing to their laminar microstructure, these coatings showed a cohesive delamination with an adhesion strength of 10 MPa. Results demonstrated that these coatings were able to reduce the corrosion of carbon steel in saline water by 99.7%, with corrosion rates of 38.33 mpy for carbon steel, and 0.099 and 0.155 mpy for SiC/C and SiC/C/Al (10 µm) coatings, respectively.
