Corrosion Behavior of Silver with a Special Reference to Electronics Application

Abstract

Metallic materials used in electronic components and devices corrode in the same ways as automobiles and bridges, but their small dimensions make them orders of magnitude more susceptible to corrosion failure. The corrosion involves interactions with environment. These interactions can be put to use under control. This article presents the tarnishing film formation characteristics of silver as the first part of a series of articles describing corrosion behavior of silver in electronics application. The mechanisms and processes of tarnishing are discussed and indoor tarnishing film formation rates are presented.
