Niobium coating applied by HVOF as protection against hydrogen embrittlement of API 5CT P110 steel

Artificial neural network to predict the degraded mechanical properties of metallic materials due to the presence of hydrogen

“…Results proved that the combined effect of alumina, aluminum, and Fe-Al layers in three-layer coating exhibited excellent hydrogen entry resistance [13]. Brandolt et al provided Niobium coating over the surface of steel substrate and the evaluation of mechanical properties after hydrogen charging states that Niobium acts as a barrier for hydrogen diffusion thereby minimizing the effect of hydrogen in mechanical properties [14]. Dieudonne et al studied the role of copper and aluminum content in Twinning Induced Plasticity steel on hydrogen embrittlement susceptibility and concluded that steel with high copper and aluminum content increases the hydrogen embrittlement resistance [15].Beryllium -copper alloy was hydrogen charged by Ogawa et al and the hydrogen diffusivity, solubility and mechanical properties was evaluated.…”
