Fungal Influenced Corrosion of Metals in Humid Environments.

Abstract

Case studies of atmospheric corrosion will be reviewed in which fungi produced localized corrosion of bare metals and disbonding of coatings. In relative humidities of 65% or greater with adequate nutrients, fungi can thrive and produce acidic by-products, including oxalic, lactic, acetic, and citric acids. Fungi can derive nutrients from soil; cellulosic materials (grains, paper, composition board, and wood); hydrocarbons (crude oil, fuel oil, jet fuel, kerosene, greases, waves, lubricants, and adhesives); organic coatings and numerous other sources. Case studies will identify causative organisms, sources of nutrients, corrosion mechanisms, and possible remedies.
