HVOF - Jet Kote™

null

In a typical HVOF process, the continuous combustion of a gaseous fuel & oxygen mixture occurs within a combustion chamber. Alloy and/or composite powders are introduced axially into the nozzle where they are heated and accelerated. The resulting exhaust/powder stream exits the nozzle at extreme high velocity in a tightly collimated flame whereupon particles impact the surface of the workpiece, forming a dense coating with excellent bonding properties.

Kennametal Stellite’s™ Jet Kote™ systems, first introduced in 1983, have a long legacy of producing the highest quality coatings on the market. The differentiated design coupled with robust engineering provide high particle velocities, oxide control and extremely dense coatings (<1% porosity). The Jet Kote™ system is capable of spraying materials at rates of up to 22 lb/hr, allowing for maximum control of throughput and efficiency.
