Coating for the Protection of Structural Steelwork

page. Coating for the Protection of Structural. Steelwork. This is an update of a DTI publication first issued in 1982. The new version has been prepared by Dr. R. .. case, either zinc or aluminium can be used. The metal, in powder or wire form, is fed through a special spray gun containing a heat source which can be either

Corrosion protection -

Thermally sprayed coatings of zinc, aluminium, and zinc-aluminium alloys can provide long-term corrosion protection to steel structures exposed to aggressive environments. The metal, in powder or wire form, is fed through a special spray gun containing a heat source, which can be either an oxygas flame or an electric arc.

FHWA Bridge Coatings Technical Note: Metallized Steel Bridge

For corrosion control coatings on steel structures, metallizing refers to the thermal spraying of zinc or aluminum alloys as a coating directly onto steel surfaces. The coatings are created by using a heat source (either flame or electric-arc) to melt the metal which is supplied as a wire or in powder form. An airstream sprays the

Metallizing for Corrosion Control - Introduction

The metalizing process always begins with proper surface preparation. Next, aluminum wire or zinc wire is continuously melted in an electric arc spray or gas flame spray gun. Clean, compressed air strips droplets of molten metal from the wire depositing these particles onto the steel forming the protective coating.

Thermal spraying - Wikipedia

Coating materials available for thermal spraying include metals, alloys, ceramics, plastics and composites. They are fed in powder or wire form, heated to a molten or semimolten state and accelerated towards substrates in the form of micrometer -size particles. Combustion or electrical arc discharge is usually used as the
