What are the differences between hydrogen embrittlement and hydrogen corrosion in terms of phenomena, mechanisms, and preventive measures? I would appreciate some guidance from those with more experience.
It seems that one is a chemical reaction and the other a physical reaction; for hydrogen corrosion, the material choice matters, while for hydrogen embrittlement, the operating conditions are relevant
Hydrogen embrittlement occurs when hydrogen atoms penetrate into the crystal lattice of carbon steel, while hydrogen corrosion results from a chemical reaction between hydrogen and carbon
