In order to protect iron and steel based structures (as e. g. for steel construction, bridge construction, steel structures for water construction, onshore and offshore wind energy constructions, petrol und natural gas industry etc.) against corrosion, usually protective coatings are to be deposited. Corresponding to kind, shape, and required functionality of the part numerous procedures are available. The deposition of corrosion protection coatings or coating systems can be done by applying of hot dip galvanizing, organic coatings or thermal spraying of zinc, aluminium and their alloys. Using combinations of metallic and organic coatings corrosion protection coating systems (duplex system) can be produced. Thermal sprayed corrosion protection coatings made of zinc, aluminium and their alloys can be sprayed onto all steels for parts of the quoted industrial applications, as well as in the work shop and also on site, independent of the article´s size. Due to the usually low heat input into the surface of the part only a slight thermal loading of the substrate occurs, so that changes in steel properties and deformation of the part are not to be expected.
