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.

TesTex provides pipeline scanning services for piping that is above ground and uninsulated. The piping can be painted or have a coating and still be scanned.

Chinese scientists has reported that they have found a way to extract chemicals from discarded cigarette butts in order to protect steel pipes from corrosion.

Generally, bacteria that grow on metal exposed to moisture often secrete proteins and carbohydrates that accelerate corrosion. But a few bacteria emit compounds that retard corrosion.

The various methods that can be used to protect a metallic system against corrosion can be widely divided into: thermodynamic protection, kinetic protection, barrier protection, environmental control, etc.

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.

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.

Researchers at the Nanotechnology Research Institute at the National Institute of Advanced Industrial Science and Technology, in collaboration with Yamagata University, have succeeded in producing gel electrolytes for use in a light-control glass device using nanoparticles of Prussian blue-type complexes.

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.

PPG Industries' (NYSE:PPG) commercial coatings group has introduced ECK compound, which provides patented electrolysis corrosion "kontrol" proven to prevent dissimilar metal corrosion.

Air Liquide and Sixtron Advanced Materials announced an exclusive partnership to promote and distribute advanced coating materials to crystalline silicon ("c-Si") solar cell manufacturers worldwide.

Recently, Seattle-based Modumetal, Inc announced that it has signed an agreement with Indiana-based Steel Dynamics, Inc. (SDI) to advance the ModuGalv coating technology for application in long and sheet steel applications.

To clean up the growing oil spill in the Gulf of Mexico, engineers have begun testing a new technique to stop the leaking oil from reaching the ocean surface.
