HVOF with ethanol fuel has the following advantages:

Economy: Ethanol as a fuel requires less oxygen and lower cooling power, and the total operating cost is lower than a jet kerosene system.

Safety: Compared to kerosene fuel, ethanol is a relatively safe fuel with less harmful emissions and no carbon buildup. Therefore, Supersonic flame spraying with ethanol is more environmentally and friendly, and provides a high-quality coating.

Easy operating: Compared to kerosene, ethanol allows for oxygen-rich or neutral or fuel-rich combustion mixtures. These significantly increase the operating window, and provide the opportunity to create new advanced coatings and ensure the quality of the coatings with higher chamber pressure and faster particle velocity.
