Where Can You Buy High-Velocity Oxygen-Fuel Spraying Powder

       

Wococarbide
provides High-velocity oxygen-fuel spraying powder. Supersonic flame spraying was successfully
developed by browning company in the United States in the early 1980s, and was
first launched with jet-kote as a commodity. After several years of application
and development, the advantages of this method are gradually recognized and
accepted. Therefore, developed countries in the world have invested a lot of
financial resources in the research and development of HVOF. In the late 1980s
and early 1990s, several HVOF spraying systems were successfully developed and
put into the market. Such as diamond jet, top gun, CDs, j-gun, high velocity
air fuel, etc.

Supersonic
flame is a high-temperature and high-speed combustion flame generated by the
combustion of hydrocarbon gas such as propane and propylene or hydrogen and
high-pressure oxygen in the combustion chamber or in a special nozzle. The
combustion flame velocity can reach more than Mach 5 (1500m / s). It is usually
called HVOF (high velocity oxygen fuel). When the powder is fed axially into
the flame, the sprayed particles can be heated to a molten or semi molten state
and accelerated to a speed of 300-500m / s or even higher, so as to obtain a
high-quality coating with high bonding strength and compactness. The supersonic
flame speed is very high, but the temperature is relatively low. For WC Co
cemented carbide, it can effectively inhibit the decomposition of WC in the
spraying process. The coating has not only high bonding strength, compactness
and excellent wear resistance. Its wear resistance is much higher than that of
plasma spraying layer, which is equivalent to that of explosive spraying layer,
but also exceeds that of electroplated hard chromium layer and spray melting
layer.
