Thermal coatings

Optimise quality &
Conserve resources.

In thermal coatings, various spraying methods are available that differ based on the type of spraying filler material, the manufacturing or the energy carrier. The individual thermal spraying methods do not compete in their application, rather they complement each other with their specific process characteristics and are adapted to the demands of our customers.

Report about Horn in Chemiereport

The sculpture “Sparefroh!“ (Happy Saver) – as an original representation of the large savings potential through correct coatings – adorned the cover of “GTS Strahl”. The Austrian professional journal “Chemiereport” published an extensive report on the topic of “Thermal coatings” about the company Horn and our special expertise. You can catch up now …

Flame spraying with wire

The coating material, available as wire, is fused in a burner and the accruing particles are applied to the coated surface in the gas stream.

Flame temperature: 3160 ° C 5720 ° F
Particle speed: 100 to 200 m/s   325 to 650 fs/s

Flame spraying with powder

Flame spraying with powder
is just like any coating form – but the coating material is applied in powder form.

Flame temperature: 1200 ° C  2100 ° F
Particle speed: 30 to 100 m/s   100 to 325 fs/s

Plasma spraying

A plasma (an ionized gas with a high temperature) is generated between two electrodes by fusing a powdery material and casting it onto a component.

Plasma temperature: 16000 ° C 46830 ° F
Particle speed: 80 to 450 m/s   260 to 1460 fs/s

High-speed flame spraying

A fuel is burnt in a combustion chamber. The high pressure that arises during this facilitates a gas jet that applies the fused particles to the coating material on the workpiece. Layers develop that have excellent adhesive properties.

Flame temperature: 2800 ° C 5070 ° F

Particle speed: 400 to 800 m/s   1312 to 2600 fs/s
