| Abstract Scope |
The high-velocity oxygen fuel (HVOF) process is one of the most widely used thermal spray processes for applying wear-resistant coatings to components' surfaces. Among the fuels used, ethanol stands out as a cleaner liquid fuel that does not produce soot and can be operated with various levels of stoichiometry. This research aims to analyze the influence of deposition distance, powder feed rate, and flame stoichiometry on the residual stress, deposition efficiency, and microstructure of FeCrMoB coatings deposited by an HVOF process with ethanol. An increase in the deposition efficiency with a shorter stand-off distance, fuel-rich flame, and lower powder feed rate can be observed. A significant increase in the residual stress was observed, raising the powder feed rate. As expected, the oxidized flame stoichiometry improves the formation of oxide. |
