Abstract
This study explores the hydrogen permeation resistance of Al-Si-Mg and Al-Si-Mg-Sr coated 22MnB5 boron steel in hot-press-forming. The Al-Si-Mg coating exhibits structural changes and Mg segregation, replacing the oxide layer. Sr addition is found segregated at the surface, further transforming the oxide layer. These modifications improve hydrogen permeation resistance, reducing both reversible and irreversible hydrogen permeation during hot-press-forming. Mg or Sr addition presents promising avenues for enhancing hydrogen permeation resistance in steel, potentially extending the service life of ultra-high-strength steel.
本研究探讨了铝-硅-镁和铝-硅-镁-锶涂层 22MnB5 硼钢在热压成形中的抗氢渗透性。铝-硅-镁涂层显示出结构变化和镁偏析，取代了氧化层。添加的 Sr 在表面偏析，进一步改变了氧化层。这些改性提高了抗氢渗透性，减少了热压成形过程中的可逆和不可逆氢渗透。镁或锶的添加为提高钢的抗氢渗透性提供了很好的途径，有可能延长超高强度钢的使用寿命。
