Hydrogen-Barrier Coating

Arculus’ multi-layer coating creates a hydrogen barrier, protecting substrates (e.g. hard steels) from hydrogen embrittlement and stress-induced cracking.

With its multilayer composite structure, Arculus’s coating has the following advantages: 

  1. The metal interlayer ensures physical and mechanical compatibility with the underlying metal. 

  2. The formation of extended space-charge zones at the oxide/metal interface repels hydrogen. 

  3. The strong micro-cracking resistance and the self-healing potential of the composite structure preserves hydrogen barrier performance even with measurable mechanical damage.
