HVOF torch |
In the HVOF process, powder is introduced axially into a chamber in which a gas flame is constantly burning under high pressure. The exhaust gas exits through an expansion nozzle which produces a high velocity gas stream. The powder particles are heated in this gas stream and transferred by it with kinetic energy to the surface of the work piece, forming a dense coating with excellent bonding properties.
Due to the moderate transfer of heat to the powder particles and to the work piece, which remains relatively cool, there is little metallurgical change to either the sprayed material or work piece.
We use various thermal spraying techniques to protect your components against all forms of wear, such as abrasion, erosion and corrosion. Thermal-sprayed coatings are characterized by a mechanical bonding with the substrate, which provides very good bond strength. This coating technology is very useful for temperature-sensitive base materials.
Deloro Stellite powders are gas atomised powders. HVOF & Thermal Spray powders are available in these standard size ranges:
Please see the table below for details of our HVOF & Thermal Spray powders.
Other alloy compositions may be available on request.

Powders labelled “JK” are intended primarily for HVOF spraying with the JetKote® or Diamond Jet® torches but can also be used for plasma spraying. Some of these powders may be listed below in different nominal size ranges for other thermal spray processes.
