Thermal Spray

Galvanic treatments

Main board

The processes called thermal spraying involves creating metallic, ceramic or cermet (dispersions of ceramic phases in metallic matrices) coatings starting from wires and rods or from powders of sizes between 1 and 500 µm, heated near melting point in a gas atmosphere at high temperature, and accelerated in gas flow, towards the substrate, where they solidify rapidly, giving rise to overlapping lamellar structures.


Tungsten carbide is an extremely hard material, standing at about 9 on the Mohs Scale and about 2600 on the Vickers Scale.

The coatings that use this material exhibit strong anti-wear properties as well as high hardness.


Chromium carbide, thanks to its hardness, is highly resistant to abrasion and for this reason it is recommended for protecting parts subjected to wear.

The strengths of these coatings are corrosion resistance as well as thermal shock resistance.

Chromium carbide is therefore resistant to erosion and abrasion, recommended for use in water-based solution.

The corrosion resistance is also maintained up to 870 degrees centigrade.

It is possible to apply other coatings such as CHROMIUM oxide, ALUMINUM oxide or SILICON oxide according to the specific needs of each application.
