Detonation Spray System

Sai Surface Coating Technologies (SSCT) offers a Detonation Spray System. This is used to develop dense ceramic and carbide coatings for wear resistant coatings for aero engines, power, paper, and oil and 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 International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad. Salient Features of coatings: very hard, clean and dense; have low compressive stresses; have very high bond strength; and the characteristics are superior than flame spray coatings, wire arc and plasma spray coatings. Typical coatings: anti-wear coatings, anti-corrosion coatings and metallic coatings. The company specialises in surface modification techniques and precision machining technologies. It offers diverse surface modification technologies spanning detonation spray process, high velocity oxy-fuel (HVOF) process, plasma spray, flame spray, wire arc, spray and fuse processes, plasma ion nitriding and hard facings etc, in addition to wide-spread utility precision machining and grinding facilities – a one-stop shop service for every engineering requirement.
