Investigation of the interaction between HVOF flames and surfaces based on chemiluminescence

This study examines the interaction between High-Velocity Oxygen-Fuel (HVOF) flames and surfaces from an ablation perspective, utilizing chemiluminescence as a diagnostic tool. HVOF technology, known for its high-velocity flames, is employed in ablative applications where the extreme conditions simulate environments similar to those found in space. Chemiluminescence, the emission of light resulting from chemical reactions, was used to analyze the light emitted from HVOF flames interacting with different surfaces. By capturing the emission spectra, the study identified key chemical species and monitored changes in their concentrations due to variations in flame conditions and surface characteristics. The results highlight that the nature of the surface significantly influences the ablation process. The chemiluminescent signals revealed how these surface characteristics alter the reaction mechanisms within the flame, impacting both the rate of ablation and the quality of the surface finish. In conclusion, chemiluminescence proves to be a valuable tool for real-time monitoring of the ablation process in HVOF systems. The insights gained into the interactions between flames and surfaces enhance the understanding of ablation mechanisms, leading to improved optimization of coating and material removal processes.
