Today, every manufacturer who produces API 6A products, their Valves gate plate and Valve seats will select supersonic spray, spraying tungsten carbide materials in the sealing surface. Herewith,It could make product quality is significantly higher than the spray welding ni60, ni50.The hand plasma spray welding has been gradually withdrawing from the market.

Valve plate supersonic spraying, It need spray material injection to work piece surface.

The basic characteristics of supersonic spraying:

These injected particle, after treatment, must be sufficient deformation capacity, makes its own bond to the surface of the parts. Initially, the thermal spraying technique before the impact of the heating, so that the surrounding particles into the plastic deformation, in order to reach the required technical conditions. The high velocity oxygen flame technology introduces a new method. Generated through the use of a small combustion chamber is very high (substantially supersonic) exhaust velocity, and the powdery material into the high temperature fluid can be obtained when a sufficiently high speed in order to achieve sufficient bonding. The kinetic energy of the particles is so large, in fact, that the majority of pores (a common phenomenon in the conventional coating), is substantially squeezed out. Low porosity, better coating abrasion resistance, can provide more protection.
