Thermal spraying

The term “thermal spraying” stands for different methods of surface coating. These methods can be used for metallic and non-metallic components. Depending on the desired properties, we can coat your components with pure metals, metal alloys, oxide ceramic or carbide materials. An important advantage: The surface of the components to be coated is hardly subjected to thermal stress (unlike in the case of deposition welding). Typical properties of a spray coating are also the homogeneous structure, crack free and good adhesion to the component.


Thermal spray coatings are particularly suitable for the following purposes:

  • Wear protection (abrasion/adhesion)
  • Protection against corrosion and oxidation
  • Thermal and electrical insulation
  • Targeted influencing of friction and sliding properties


How does thermal spraying work?

The materials (powder, wire) are melted or fused by means of a torch and are sprayed as spray particles onto the substrate surface to be coated. A relative movement between the torch and the workpiece produces the coating. Two types of energy influence their properties: thermal energy (fuel gas-oxygen, plasma, and arc) and kinetic energy (velocity of the particles).


Twice as good: Combine advantages

With conventional polymer coatings, you can achieve good non-stick and sliding properties. If you also require a particularly high wear resistance, we often recommend a combination of thermal spray coating and plastic coating. The thermally spray coating serves as a metallic protective matrix (EXCALIBUR® internal link), the subsequent plastic coating as a top coat. The result unites the advantages of both systems: Wear protection and wear resistance plus non-stick and sliding properties.
