High Velocity Oxygen Fuel Spray

Accuwright Industries, Inc. is expert in the applications of all metal spray processes, especially the High Velocity Oxygen Fuel (HVOF) process for all industries and applications. Providing exceptionally hard, dense coatings from materials recognized for wear and long life purpose. With super-sonic shock diamonds in its line of fire, this fast hard-hitting process puts down coatings like no other thermal spray process.

Fully automatic and robotically controlled, this process is repeatable and dependable from start to finish. Utilizing mass flow control with memory features, this system can retain and store process recipes for easy fingertip recall. Process friendly to accommodate even the most diverse spray applications the system includes indexing and turning capabilities for a wide range of unique applications that can be used together or standalone.

With an industry standard material list, this HVOF process leads the way for unique and exceptional spray designs and applications. Designed with difficult and challenging concepts in mind, this flame spray process exceeds most other thermal coatings for bond strength and integrity.

Whether you need hard surface wear that’s resistance to abrasion, or just a super dense coating, this automated process will make specification control your guide.

Description of High Velocity Oxygen Fuel Spray

High Velocity Oxygen Fuel (HVOF) Spray introduces a unique method of spraying metal powders. The process utilizes a combination of oxygen with various fuel gases including hydrogen, propane, Propylene and even kerosene in the combustion chamber, and burning by-products are expanded and expelled outward through an orifice producing extreme velocities. Often times they produce "shock Diamonds" exiting the spray gun in the flame of the High Velocity Oxygen Fuel (HVOF) Spray gun. Powders to be sprayed via HVOF are injected axially into the expanding hot gases where they are propelled forward, heated and accelerated onto a surface to form a coating. Gas velocities exceeding Mach 1 have been reported with temperatures of 2,300°C. The coupling of inertial driven/highly plasticized particles can achieve coatings approaching that of theoretical density. These coatings are hard, dense and well bonded to improved components.
