AB  - The effect of hydrogen on the microhardness of pure copper was investigated after
experiments conducted on specimens that hydrogen charged under different cathodic charging
conditions. Microhardness measurements revealed that the introduction of hydrogen caused hardening
on the surface of copper. The severity of the hardened region increased with either cathodic current
density or charging time. Further charging increased the depth of the hardened region of copper.
Ageing after charging can result in either complete or partial recovery of hardness, depending on the
charging conditions.
