Corrosion protection measures are divided into active and passive processes. Electrochemical corrosion protection plays an active part in the corrosion process by changing the potential. Coatings on the object to be protected keep the aggressive medium at a distance. Organic coatings applied primarily to...
Back Technical article Metallic coatings for corrosion protection My bookmarks Overview of metallic coated products The corrosion resistance of a metallic coating is not only defined by the thickness of the coating. Its chemical composition is also critically important. Today, the best-known steel ...
Corrosion damage to powered roof supports used by the National Coal Board has resulted in high refurbishing costs. This paper describes a project to assess metallic, paint, and plastic coatings for protecting components of supports. The project consisted of evaluating the performance of coatings in ...

The upper temperature limit for this high temperature tape system is 121°C (250°F). The cold-applied coating for steel circular pilings in marine environments is a six layer composite module which combines corrosion inhibitors and high mechanical strength. The modules are drawn around the ...
corrosion protection properties due to lower porosity and lower cracking potential along with enhancement of the mechanical properties.Furthermore,the incorporation of inorganic nanoparticles can be a way to insert corrosion inhibitors,preparing inhibitor nanoreservoirs for "self-repairing" pre-treatments ...
and limitations. The main precursors used in the synthesis of OIH sol–gel coatings for corrosion protection are also discussed, according to the metallic substrate used. Finally, a multilayer system to improve the resistance to corrosion is proposed, based on OIH coatings produced by the sol–gel...
Extensive metallographic, corrosion and hydrogen embrittlement tests have been carried out with high strength steel sheet coated with ion vapour deposited (IVD) aluminum. Metallography showed that the thickness of the as- deposited IVD coatings was not uniform and that the coatings contained extensive ...
This study demonstrates the influence of ceramic nanocontainers loaded with corrosion inhibitor 2-mercaptobenzothiazole into hybrid organic–inorganic coatings on the corrosion protection of hot dip galvanized steel. The corrosion resistance of these coatings was evaluated using electrochemical impedance spectrosc...
