AVARTANA METAL  POWDERS are produced by VACUUM INERT GAS ATOMIZED  and cooled in Argon/nitrogen inert gas. This process allows AVARTANA METAL  POWDERSto produce spherical, not oxidised particles with a homogeneous chemical com- position. Powder is sieved using ultrasonic sieving to obtain a precise grain distribution according to the different applications for Base metals like Nickel, Cobalt, Hard Facing  /Plasma Transferred Arc(PTA) powders/Additive manufacturing  powders/Thermal Spray powders..etc

 

Self-Fluxing Alloy Powders are a type of thermal spraying (welding) materials which have functions of self-deoxidization and self-slag formation when melting. The nickel-Chromium- Boron-Silicon series of self-fluxing alloy powders have been successfully used for equipment manufacture and maintenance in the metallurgical, petroleum, chemical and machinery manufacturing industries. Self-Fluxing Alloy Powder can be applied by spraying or welding using commonly available oxygen-acetylene equipment. During thermal spraying or welding, the molten alloy forms a metallurgical bond with the substrate surface. Coatings thus formed are very dense, wear and corrosion resistant up to medium temperatures and adaptable for hard facing gears, dies, valves and other mechanical components vulnerable to wear.
