“…The MoS 2 layer usually exhibits a good adhesion performance because the sulfur atom can bond tightly to a metal surface. Li et al 71 analyzed the hydrogen transfer energy between a MoS 2 layer and an Fe (111) surface by spinpolarized density function theory (DFT). It was found that the hydrogen adsorption energy on the surface increased from 0.55 to 1.26 eV, which proves that MoS 2 can be used as a hydrogen barrier.…”

“…Deyab and Keera explored [18], 1.0 M H2SO4 corrosion prevention for carbon steel was explored using a coating system containing nano -TiO2 particles of varying sizes (10, 50, 100, and 150 nm). These nano-TiO2 particles increased the corrosion resistance of coatings In 2015 Motonori Tamura [19] Stated that coating with Al2O3, TiC, or TiN reduced the hydrogen permeability of the 316L austenitic stainless steel twice as much as the uncoated substrates, Xinfeng Li and others in 2019 studied the action of surface roughne ss on the hydrogen blistering in steel, It was found that ground s urfaces that have greater roughness showed compressive residual stress in compression to polished surfaces the ground test specimens offers less sensibility to hydrogen blisters compared with the polished test specimens [20] in 2020 Muhammad Wasim, and Milos [21] studied the influence of hydrogen penetration of low-carbon steel at macro-, micro-, and nanoscales in the hydrogen-rich acidic atmosphere. The results proved that there is a directly proportional relationship between the concentration of hydrogen and corrosion rate with increasing charging time,…”

 A third coating layer gives an acceptable adhesion force with the highest deposition rate.  Nano-structured coating increased bulk AISI 1018 steel tensile strength after the hydrogen charging process.  Double layer of Ti and TiO2+Al2O3 coat gives a 20 percent increase in tensile strength after HC for AISI 1018 steel.  The layer of ceramic coatings TiO2withAl2O3 as coating Nano-structured thin films can improve the hydrogen permeation resistance  The Nano titanium layer showed the main portion in bondingHydrogen embrittlement is a diffusible Hydrogen that is harmful to the toughness of iron. It follows, therefore, that the harmful influence of diffusible Hydrogen can be mitigated by preventing its entry into steel. This approach was achieved by using three coating layers as a coating nanostructure thin layer by DC sputtering on steel structural (AISI l018) and hydrogen charging (HC) effect on uncoated and different Nano coated tensile specimens. The first layer was Titanium as a bonding layer, the second layer was TiO2 with Al2O3, and the third layer was Al2O3. Using a titanium Nano layer coating on AISI1018 steel tensile specimens increased the tensile strength from 570 to 659 M Pa with 16 hours of charging, which is considered a good increase. In contrast, the elongation remained in a steady -state with little difference in values compared to changing the charging time and the coating of the double layer. Furthermore, it was found that samples coated with TiO2 and Al2O3 by the DC method had advanced hydrogen embrittlement resistance and increased tensile strength (from 565 to 680 M Pa with 8 hours of charging process). M oreover, the maximum adhesion value was related to the triple layer at 596 psi, and the lowest value was 309 psi using the titanium layer alone. The coating time was 5 hours of the sputtering process for all specimens.The coating layers are considered a good barrier for hydrogen permeation through steel structures (AISI 1018).

Hydrogen embrittlement (HE) has been extensively studied in bulk materials. However, little is known about the role of H on the plastic deformation and fracture mechanisms of nanoscale materials such as nanowires. In this study, molecular dynamics simulations are employed to study the influence of H segregation on the behavior of intergranular cracks in bicrystalline α-Fe nanowires. The results demonstrate that segregated H atoms have weak embrittling effects on the predicted ductile cracks along the GBs, but favor the cleavage process of intergranular cracks in the theoretically brittle directions. Furthermore, it is revealed that cyclic loading can promote the H accumulation into the GB region ahead of the crack tip and overcome crack trapping, thus inducing a ductile-to-brittle transformation. This information will deepen our understanding on the experimentally-observed H-assisted brittle cleavage failure and have implications for designing new nanocrystalline materials with high resistance to HE.
