【 摘 要 】

The effect of hydrogen on the microhardness of pure copper was investigated afterexperiments conducted on specimens that hydrogen charged under different cathodic chargingconditions. Microhardness measurements revealed that the introduction of hydrogen caused hardeningon the surface of copper. The severity of the hardened region increased with either cathodic currentdensity 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 thecharging conditions.
