“Blistering is a process resulting in dome-shaped defects visible on the surface of an object and arising from localised loss of cohesion below the surface.
NOTE: For example, blistering can occur on coated metal due to loss of adhesion between coating and substrate, caused by accumulation of products from localised corrosion. On uncoated metal blistering can occur due to excessive internal hydrogen pressure.” (DIN EN ISO 8044: 1999) |
