Analysis of Discolored and Corroded Components

Discoloration and corrosion of components can lead to a wide variety of problems, ranging from poor cosmetic appearance to complete deterioration. Whether a component undergoes superficial surface discoloration or severe corrosion, a systematic approach is needed in order to properly identify the cause of the problem so that proper corrective measures can be taken. Many different analysis techniques are available for characterizing surface discoloration and corrosion deposits, and the proper use of the appropriate techniques will greatly increase the likelihood of correctly identifying the physical cause of the problem. This article details an effective failure analysis process for evaluating discolored and corroded parts.
