Corrosion in boilers by the attack of oxygen

Without proper mechanical and chemical deaeration, oxygen in the feed water  enters the boiler. Much is flashed off with the steam; the remainder can attack boiler metal.

Corrosion in Boilers

Corrosion may be produced general attach over a large metal surface or it may result in pinpoint penetration of the metal. Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.

Biological coating could prevent metal corrosion in seawater

Corrosion in seawater is caused when metals react with minerals in the water and produce hydrogen sulfide. Current technologies make use of biocides and inhibitors to prevent the generation of hydrogen sulfide, but treating metals with these materials proves to be costly, ineffective and often causes toxicity to aquatic life.

Bacterial Sulfate Reduction Effect on Iron-Corrosion Scales

Iron-sulfur geochemistry is important in many natural and engineered environments, including drinking water systems. In the anaerobic environment beneath scales of corroding iron drinking water distribution system pipes, sulfate-reducing bacteria produce sulfide from naturally occurring sulfate in the bulk water. This sulfide subsequently can affect iron geochemistry of the scale and the protective qualities of the scale.

Coatings Technology for Corrosion in Marine Applications

For marine applications, mild steel remains the number one metal for constructional purposes by virtue of its relatively low cost, mechanical strength and ease of fabrication. Its main drawback is that is corrodes easily in seawater and unless adequately protected, rapidly loses strength which may result in structural failure.
