High velocity flame spraying

High-velocity-flame sprayingWith this thermal spraying technology, coatings of premium quality, density and hardness are produced. A wide variety of materials can be processed. A typical application for this process is metal carbide coating for extremely abrasive loads.

An oxygen-flammable gas mixture is ignited inside a combustion chamber, which has a nozzle that accelerates the rapidly expanding gas to supersonic speed.

Using an inert carrier gas, the powder-type coating material is fed into the process in a regulated manner and is also accelerated to a supersonic speed.

In addition to thermal energy, the sprayed particles also take on a great amount of kinetic energy, which gets converted into additional thermal energy when they strike the surface to be coated. This results in a high degree of spray particle deformation, which leads to well-bonded and extremely dense coatings.

With a hardness of well over 1000 HV, such coatings offer a wide variety of solutions for the problems of abrasion.
