ISTT Resident Company Develops New Thermal Spray System
June 22, 2019

Behboud Sanat Mahan, a resident company at Isfahan Science and Technology Town (ISTT) has been able to domesticize and utilize the new global thermal method for spraying, also known as High Velocity Oxy Fuel Thermal Spray System (HVOF/HP).

The HVOF process efficiently combusts oxygen and a gaseous or liquid fuel to produce high kinetic energy with controlled heat input. The coating material, in powder form, is introduced into and uniformly heated by the hot gas stream to a molten or semi-molten condition. The flame and powder are accelerated by a converging / diverging nozzle spray gun to produce supersonic gas and particle velocities, which propel the powder particles toward the substrate to be coated. The powder particles flatten plastically upon impact with the substrate; cooling and solidifying to form the coating. This thermal system creates a velocity of 1200-1500 m/s (approx. 5 times the speed of light).

Behboud Sanat Mahan is a knowledge based start-up that has been settled at ISTT since 2016. Apart from developing and utilizing the new thermal spray system in Iran, this company has also been active in the production of steel, ceramic, super alloy and cermet coatings that provide resistance to adhesive wear and erosion, not to mention cladding and Plasma Nitration.
