摘要：

Passive layers on Ni and Fe53Ni formed in alkaline and acidic electrolytes have been studied by XPS. Both metals form an oxide barrier with NiO as constituent growing according to a high field mechanism. In alkaline solutions a Ni(OH)2 containing overlayer is found. Characteristic shifts of the XPS and UPS signals in the transpassive range are interpreted by a change of Ni(OH)2 to NiOOH on the basis of a simple semiconductor model. The features of the polarization curves can be closely related to the the surface analytical results. © 1990.
