Inorganic Coatings – Determination of Coating Thickness – Coulometric Method by Anodic Dissolution. ISO 2177:2003 describes a coulometric method for determining coating thickness through anodic dissolution. This method is primarily used for metallic coatings and involves dissolving the coating by applying an electric current, then measuring the dissolution rate to determine thickness. It is a precise and rapid method, particularly suitable for coatings used in electronics and fine mechanics. The standard provides detailed procedures, including electrochemical settings and result interpretation.
