Description

Dehydrogenation: enhance the toughness of the substrate metal and coating

Dehydrogenation

When parts are pickling, cathode plate deoiling and electroplating, hydrogen may ooze in the lattice of coating and substrate metal, resulting in lattice distortion, increased internal stress and brittleness.
