“…For target-trap spraying, PG-C27 "Sormite" powder coating products were taken according to thermodynamic requirements and we sprayed it on the target-trap in a gas flame. To create a high-temperature flame, we used C₂H₂ -acetylene gas involved in theoretical calculations and oxygen for its oxidation (combustion) [2].…”

“…Therefore, determining whether the powder mixture selected for spraying is suitable for spraying in a gas flame stream is one of the important issues for obtaining quality abrasion-resistant coatings. To determine the suitability of powder mixtures for spraying in a gas flame, we analyzed the thermodynamics of their interaction with water vapor in the gas and oxygen in the atmosphere using the aggregate state of powder particles flowing through zones of the gas flame with different temperatures [2].…”

The thermodynamic indicators of each of the metals in the PG-C27 (Sormite) powder coating product were calculated at different temperatures and the composition of the reactive gases resulting from the combustion of the gas flame, which is widely used in the production of corrosionresistant coatings on the surface of details in a gas flame. It was determined that Cr-chromium, Feiron, and Ni-nickel powder particles flowing together at the temperature of 1800 °C in the central core of the gas flame and the combustion reaction medium do not oxidize. The Cr-chromium powder particles contained in the powder mixture flowing from the inner side of the gas flame are oxidized by the water vapor produced by the gas combustion. However, it was found that Fe-iron and Ni-nickel powder particles in the flow are not oxidized. It was revealed that all metal powder particles in the powder mixture are completely oxidized due to the effect of water vapor and oxygen on the outer side of the gas flame.
