Abstract :
Hydrogen charging of copper can be possible by three different methods, first is cathodic charging, second
gaseous or high temperature charging and third electroless copper plating. The effect of hydrogen on copper is that
it changes physical and mechanical properties. Above three methods concluded that hydrogen effect shows two
different courses first, the development of high pressure molecular hydrogen in voids and second formation of defect,
such as dislocation due to precipitation of absorbed atomic hydrogen in the form of hydrogen molecules and due to
this region physical and mechanical property of copper changing with hydrogen charging.
