PlasmaCoat®: plasma spray coatings and thermal spraying

The PlasmaCoat® thermal spray system by Argos ST combines hardness and abrasion resistance through thermal spraying.

The advantages of PlasmaCoat®

The thermal spraying system, better known as PlasmaCoat®, combines the exceptional hardness and abrasion resistance of thermal spray coatings, also technically called thermal spraying, with the non-stick and sliding properties typical of polymers.

With spray metallizing, the structural characteristics and surface roughness can be modified to give the final coating excellent traction or slide.

How does the PlasmaCoat® technology work?

This type of coating, which relies on thermal spraying, lends the base materials all the desired properties of ceramics: elevated hardness and wear resistance, electrical insulation or conductivity, low thermal conductivity and a reproducible surface structure.

In plasma thermal coatings, powders or mixes of ceramic powders such as stainless steel, nickel/aluminium, tungsten carbide, zinc and chromium oxide, are melted in a plasma torch and applied to the sandblasted metal surface.

In general, choosing PlasmaCoat® thermal spray coatings means obtaining:

  1. Great sliding properties:

    These coatings give any material the well-known and extraordinary sliding features of fluoroplastics. With their lower coefficient of surface friction, Argos coatings can be safely defined as anti-wear coatings.

  2. Greater hardness:

    By coating surfaces with various metals or ceramics via thermal spraying, the hardness of the components can be greatly increased, especially in the presence of abrasive materials such as paper and fabrics.

  3. Traction optimization:

    Choosing an Argos thermal spray coating also means being able to improve the traction of the material. In fact, thermal spraying modifies the surface structure and roughness, combining processes and coating materials.

  4. Non-stick properties:

    Coatings applied using the PlasmaCoat® process create surfaces with extraordinary non-stick and perfectly hydrophobic properties.

  5. Optimal performance in high-temperature environments

    With a wide range of metals, ceramics and polymers, customized solutions can be developed for each individual application.
