Carbide coatings

Maximum reliability due to extreme wear resistance, excellent bonds and low porosity.

Thermal spray powders alloyed with carbides are applied to increase wear resistance. The hard carbide parts in combination with a ductile matrix produce extreme hardness and extreme wear resistance.

WC-based (Wolfram carbide) powders

Thermal spray powders that contain wolfram carbides can be used for process temperatures below 500˚C.
Wolfram carbide coatings are characterised by their extreme wear resistance; adding chrome increases the corrosion resistance enormously.
This makes WC coatings extremely suitable for the high requirements imposed by the steel, paper & pulp, oil, gas and petrochemical industry.

Cr3C2-based (Chrome carbide) powders

At process temperatures that exceed 500˚C wolfram carbide coatings are unable to provide the required oxidation resistance. At higher process temperatures up to 870˚C coatings based on chrome carbide are better resistant against high-temperature corrosion.
Together with a bond material, ranging from 10 to 50 percent, the hardness and ductility combination is tailored to the client's specific application requirements.

Combined powders

Coatings with a combination of both carbide materials in a high alloyed matrix, for example Inconel or Hastelloy, give the coating a greater resistance against corrosive and oxidative environments, such as acids and lyes.
Combined coatings can be used in process temperatures of up to maximum 700˚C.
