ABSTRACT:
A surface coating on an insulative material substrate, assuring protection against electromagnetic interference in corrosive environments, comprises two stacked metallic layers. The first layer, in contact with the substrate, is a layer of nickel-based alloy containing about 2% to 20% by weight of an element from group V B from the Periodic Table of the Elements. The second, surface layer is a layer of silver or one or its alloys. Applications include insulative material cases for electrical or electronic components including a shield consisting of a surface coating of this kind.
