Hydrogen Embrittlement Relief
Hydrogen Embrittlement Relief refers to the removal of hydrogen from ferrous metal components that have been electroplated. Hydrogen will form and be partially absorbed during the electroplating process at component's surface.
If left untreated the atomic hydrogen, which has been absorbed by the metal, can combine with other atomic atoms, such as oxygen, and form water vapor. This can cause micro-cracking. Micro-cracking can lead to premature part failure.
