HVOF or high velocity Oxy-fuel thermal coating is a state-of-the-art coating process, where particles of harder material are accelerated at a high temperature in a pressure ﬂame generated from the combus on of liquid fuel and pure oxygen. The accelerated high temperature particles are fused into the base material’s surface creating a layer with enhanced mechanical properties. HVOF coatings mainly provide high wear and corrosion resistance in addition to protection against galling of sliding surfaces.
Currently we are providing coating solutions with tungsten carbide and Stellite 6® materials, with the capability of spraying several other types of materials at the customer’s request and depending on compatibility with our system.
The main beneﬁts of thermally sprayed tungsten carbide coating are:
Typical applications of tungsten carbide coating include:
– MTM technology ball valves and seats
– Gate valves
– Valve actuators
Our current set-up also includes ﬁne surface finishing capabilities for the above materials, such as surface grinders and lapping equipment.
