Abstract
The High Velocity Oxy-Fuel (HVOF) system is a highly promising technique for the production of thermal barrier coatings (TBCs), helpful in the protection of materials exposed to extreme thermal and corrosive environments. Coatings generated through the technique are employed in industrial settings to extend product life, increase performance and decrease maintenance costs. HVOF yields lower porosity and higher adhesion TBCs when compared to similar thermal spraying processes. Though gas fuelled systems are the norm in this technique, there is a recent interest in employing liquids due to their low cost and increased deposit density. Economic and highly scalable, HVOF process optimization is key to the development of next-generation systems. The work presented in this investigation focuses on the design and manufacturing of a liquid-fuelled HVOF gun through the individual consideration of design aspects and test equipment components. A flammability investigation for gas is performed on the manufactured prototype; to accompany the study a CFD model is developed and presented for future comparisons. Further investigations on the subject and system will focus on the transition to liquid fuel in the model and the study of coating particle trajectories.
