To avoid this, electrically isolate the coil in the tank. Zinc is 99.9% pure and does not cause contamination during the deposition process. Consequently, thermally sprayed zinc coatings more friendly than those used in the process hot galvanization, such as nickel, which is used in electroplating, contains a large amount of iron impurities. Continue to learn more with: Startapp. Aluminum is usually clear in 99% and is used in the most corrosion-resistant work. The advantages of zinc and aluminum coatings.

The choice of metal for thermal spraying. SredMetall Alkaline Zn Polluted Acid Al Al Al Hot water Sea water AlMg5 Cathodic Protection Zn Zn or mechanical damage Arc spraying Al Aluminium: Resistance to high temperatures, light, good resistance to polluted marine environments, forming oxide layer, which reduces the permeability of the surface and ostananvlivaet corrosion. (Similarly see: Sander Gerber). Zinc: Suitable for cathodic protection, good resistance to mechanical damage, life is proportional to the thickness of the coating (if not used impregnation) is used in corrosion primers. Sputtered aluminum to withstand the action of many divorced acids (with pH 3.5 and above), the lifetime of the coating is determined by the chemical composition of the reactants and type of surface. Highly dilute solutions of nitric oxide and sulfuric acid, as well as many organic acids have little effect on the deposited aluminum coating, if they are treated with impregnation.

Deposited zinc poorly resists the action of almost all the acids, both organic and not organic. Zinc coatings are used mainly in the pH range from 6 to 12. As with the deposition of zinc coatings, service life is determined by film-forming nature of the medium. Resistance to zinc in hard water more than soft. He has poor resistance to any type of water at a temperature above 24oS. Spramet-anticorrosive paint as an alternative to testing sprayed metallic coatings for resistance to external shocks, showed that they have a longer lifespan than the coatings obtained during dyeing, which involves trained steel products and the implementation of appropriate procedures during use.
