Thermal metal spray coatings in accordance with DIN EN 2063 and NORSOK M-501

Quality in accordance with DIN EN 2063 and NORSOK M-501

Thermal metal spraying, often also called micro-welding or metallising, comprises all coating methods in which the coating is melted with thermal energy and then sprayed onto a part surface with dispenser or combustion gases. There, the coating material hardens into an adhering metallised layer.

The most common thermal coating methods are:

  • Flame spraying,
  • arc spraying,
  • plasma spraying and
  • high-speed flame spraying.

The heat introduction into the basic material is very low in thermal metal spray coating. In contrast to, for example, application welding, this method does not produce structure changes or heat distortion.

Thermal spraying is used in particular in connection with wear and corrosion protection. Special properties such as electrical conductivity, hydrophilic or hydrophobic behaviour or special surface carrying ratios can be achieved as well.

Spray galvanisation

Spray galvanisation standardised in accordance with DIN EN 2063 sprays melted zinc onto the surface of the steel part. The layer thickness of the resulting zinc coverings usually is between 80 and 150 micrometres. Usually, spray-galvanised coatings must also be sealed with a penetrating coating.

Spray galvanisation is often used to protect such steel parts from corrosion that cannot be galvanised piece by piece due to their build. In contrast to hot-dip galvanisation, spray-galvanisation will not lead to alloy formation between the steel and zinc coating.

Thermal aluminium spray coating

Thermally sprayed aluminium (TSA) can produce a coating on steel that protects against corrosion above- and below-ground alike. This protective layer is also called the TSA topcoat. It not only actively protects the steel, but is also self-repairing to a degree.

Thermal aluminium-spray coating has a much longer service life than conventional paint systems do. This reduces repair costs in the long run.

InProCoat – thermal metal-spray coating from the specialist

Application of thermal metal-spray coats doubtlessly is one of the highest-quality corrosion protection methods in the industrial area. Our company has comprehensive competences in spray-galvanisation and thermal aluminium-spray coating, as well as separate facilities and cabins to perform such work.

We treat parts of any geometry or size with thermal metal-spray methods such as arc and flame spraying to apply layers of pure zinc or aluminium. We meet the highest demands to quality and comply with international provisions such as DIN EN 2063 and NORSOK M-501.

Blast de-rusting for surface preparation

The steel surface must be prepared accordingly to make zinc and aluminium coatings sufficiently adhesive. We conduct blast de-rusting with metallic or non-metallic blasting agents in order to clear the surface of the part to be sprayed of rust, tinder and contamination, while also increasing the degree of roughness. We can achieve any desired standard degree of purity in our various blasting facilities.
