Abstract [en]

In exposure of copper to water molecules there will be relatively strong bonds (reversible traps) between copper and hydrogen. One copper-hydrogen bond corresponds to the thermal energy of a temperature of approximately 250 degrees C and this explains an unusual temperature influence on hydrogen uptake in the metal and in corrosion of copper in pure water-vapour without O-2. This unusual temperature influence is exemplified in exposure of copper at 180 degrees C and 500 degrees C where Cu corrodes more at 180 degrees C than at 500 degrees C.
