| Abstract: | The effect of d.c., a.c. superimposed on d.c. and constant and pulsating potentials on the coercivity of electrodeposited Ni-Fe alloy thin films obtained in a sulphate-tartrate bath has been investigated. It has been shown that the dependency of coercivity on current and potential parameters passes through a minimum. This phenomenon is related to the current efficiency of hydrogen production and to the alloy composition. |
