Main performance:

Resistance to abrasion and erosion --- hardness;

Hardened layer, avoiding shedding and cracking --- bonding strength and stress control; 

Low sealing rate and leak rate --- machining precision; 

Reliable use ---reasonable design of process and structure.

€-High-Velocity Oxygen Fuel (HVOF)

The hard surface treatment adopts the spray coating system of the world-famous SUCZER METCO, namely the high-velocity oxygen fuel (HVOF) in aerospace technology with the world patent: the spraying gun, designed with patented technologies, sprays the metal powder onto the metal surface with high-velocity air at 3 machs to form a high-strength coating. The hardness of the surface’s hardened layer is different subject to the sprayed material and the Rockwell hardness can exceed HRC70, thus playing a big role in preventing the granular medium from washing the sealing surface.
