HYDROGEN EFFECT ON THE TRANSFORM FROM CRYSTAL TO AMORPHOUS CONSTRACTURE OF PLATING Ni FILM
Ni镀层由晶态向非晶态结构转变的氢效应

Effect of hydrogen on the transformation of the plating Ni film structurewas studied.Pre-charging hydrogen in A_3 steel substrate and decreasing the bath pH bothcan promote the transformation from crystal to amorphous state.It was proved that theadsorbed hydrogen on the electrode surface played an imporbant role for this transforma-tion.
