Detonation Spray Process
Detonation Spray system used to develop dense ceramic and carbide coatings for wear resistant coatings for Aero engine, Power, Paper, Oil & refinery Sectors.
In Detonation spray system, an explosive high temperature flux of gas mixtures (Acetylene and Oxygen) is used as a source for heating, accelerating and spraying the powder particles. The high temperature, high velocity gas products of the detonation melt the particles and accelerate them sufficiently so that they emerge from the gun at supersonic velocities depending upon the material being sprayed and its powder size characteristics. The resulting high velocity impingement of the particles on the substrate yields very dense coatings with excellent adhesion.
This technology was developed and transferred by Advanced Research centre for powder metallurgy and new materials (ARCI), HYDERABAD.
