Optimization and Improvement of a Novel HVOF Process Fueled with Ethanol

2022

The high velocity oxy-fuel (HVOF) spray has become a process of choice for producing high performance cermet or alloy coatings. Common HVOF thermal spray systems classically use the combustion of gases, such as hydrogen, propane or a liquid fuel such as kerosene. However, there is currently a limited amount of literature on the use of ethanol as a fuel within HVOF processes and the performances of the resulting coatings are not well documented. Ethanol benefits from environmentally friendly features and is less polluting compared to conventional fossil liquid fuels (i.e. kerosene) as its combustion generates less nitrogen oxides and soot particles. In this work, we decide to investigate suc…
