Carbides

carbidesCarbides Flexible application choices

Depending on the specific material chosen, carbide materials are generally best applied using High Velocity Oxygen Fuel (HVOF) spray and HVAF. When necessary, acceptable carbide coatings can be achieved using atmospheric plasma spray or combustion powder Thermos-pray.

Surface protection your specific wear needs

Thermal-sprayed carbide coatings are often the best choice to protect against:
Abrasion / Adhesion / Erosion (solid particle or cavitation) / Fretting / Impact / Galling / Sliding wear / Hard surfaces /  Complex combined wear mechanisms.
