High speed projection (H.V.O.F)

High speed thermal spray coating is based on the combustion of a fuel and an oxidizer at high pressure. This combustion produces a beam that accelerates the molten particles of the material to be projected.

With this process, dense coatings are achieved, with low porosity, and high adhesion with very small thicknesses. This procedure is also called “cold projection” because the coated parts do not reach high temperatures and thus possible deformations such as in welding processes are avoided.

High Velocity Procedure HVOF (High Velocity Oxy Fuel)

High speed projection is ideal for parts that suffer from abrasion, wear or chemical attack.

There is a wide variety of HVOF coatings, including tungsten carbides, chromium carbides, nickel chromium …
