Electric arc metallization

Electric arc metallization technology is the process of melting metal in an electric arc and spraying it on a substrate. If the metal to be sprayed is aluminum or zinc, then a corrosion-resistant metal coating is created on the substrate. There is simply no other method of protection against corrosion of bridges, power lines supports, bottom of ships.

In addition to bridges, electric arc metallization protects open metal structures, reservoirs, tanks, oil production, drilling platforms, mine copres, steel structures of dams and power plants.

Electric arc metal spraying — effective protection of metals. Adhesion when metallizing particles with a substrate occurs on a rough surface. Metallized parts do not corrode, are stable in aggressive environments, work many times longer.

The disadvantage of metallization is the porosity of the coating. Porosity is eliminated by impregnations stable in aggressive media or by painting the metallized coating. Coating, metallization and coloring are called double-layer combined. Such coatings serve longer than each of the constituent coatings.

Coating with metallizer is applied. The substrate is previously shot (sandblasted). Degreasing. The metallization layer is melted onto the substrate by a jet of molten metal. The electric arc metallization process is intermittent, the substrate cannot be overheated and temperature stresses between different metal layers cannot be allowed to rise.
