Introduction to Hvof Tungsten Carbide Coating
Cemented Carbide Valve Seat
Valve Seat: The detachable surface parts in valve are used to support the valve spool in the fully closed position and constitute a sealed part. Generally, valve seat diameter is the maximum flow diameter of the valve. 
Brief Introduction
High-velocity oxygen-fuel is a new thermal spray technology invented by Browing in the United States in 1981. Nowadays, it is generally called HVOF (High-velocity oxygen-fuel). The flame generated by this technology is a high-temperature, high-speed combustion flame flow generated by using a hydrocarbon-based gas or hydrogen such as propane or propylene, and high-pressure oxygen in a combustion chamber or in a special nozzle. The velocity of the combustion flame can reach more than five Mach (1500 m/s). The axial direction of the powder is fed into the flame, and the sprayed particles can be heated to a molten or semi-molten state. Accelerate the velocity of the combustion flame to a speed of up to 300-500 m/s or even higher, resulting in a high-density, dense, high-quality coating.
