Supersonic Tungsten Carbide Coating for Injection Molding Machine Screws

The SX-8000 supersonic flame spraying system is a new type of HVOF system. Its basic principle involves atomizing kerosene thoroughly using an atomizing nozzle to produce a combustible mixture, which is then fed into the combustion chamber along with an oxidizer—oxygen. After being ignited by the ignition system, the high-temperature, high-pressure gas is further accelerated and burned through a Laval nozzle, generating a high-temperature, high-pressure supersonic flame jet. Meanwhile, the powder feeding system delivers powder materials from a low-pressure zone into the flame jet, where they are heated and accelerated before being sprayed onto the workpiece surface to form a high-quality coating.

Product Description

Supersonic Tungsten Carbide Coating for Injection Molding Machine Screws

The SX-8000 supersonic flame spraying system is a new type of HVOF system. Its basic principle involves using an atomizing nozzle to thoroughly atomize kerosene after introducing combustion-supporting oxygen, thereby forming a combustible mixture that enters the combustion chamber. Once ignited by the ignition system, this high-temperature, high-pressure gas flow is further accelerated and burned through a Laval nozzle, generating a high-temperature, high-pressure supersonic flame jet. A powder feeding system then delivers powdered materials from a low-pressure zone into the flame jet, where they are heated and accelerated before being sprayed onto the workpiece surface to form a high-quality coating.
