“…Since, it is known that when the temperature rises to 950-1250 • C, γ-Al 2 O 3 turns into thermodynamically stable α-Al 2 O 3 . This transformation can proceed directly or through intermediate phases such as δand θ-Al 2 O 3 [31,32].…”

Al2O3 coatings were applied on the surface of 12Ch18N10T steel by the detonation method at different degrees of filling of the detonation gun. The aim was to study the influence of technological parameters on the formation of the coating’s structure, phase composition and tribological characteristics. The degree of filling the gun with a gas mixture (C2H2/O2) varied from 53% to 68%. X-ray diffraction study showed that the content of α-Al2O3 increases depending on the degree of filling. The results showed that the hardness increases with an increase in the α-Al2O3 phase. When the gun is 53% filled with gas, the Al2O3-based coating has the hardness of 20.56 GPa compared to 58%, 63% and 68% fillings. Tribology tests have shown that the wear rate and friction coefficient of the coating is highly dependent on the degree of filling of the gun.

This study investigated the structural-phase, morphology, elemental composition, and tribological properties of coatings systems based on Al2O3, NiCr, and NiCr-Al2O3 fabricated by detonation-gas spraying method in a nitrogen/propane atmosphere. The coatings were characterised using SEM-EDX, XRD, Raman spectroscopy, and hardness measurements, and results analysed are presented. According to the experimental data, an optimal mode was selected that provides an increase in mechanical and tribological characteristics, and a method for detonation spraying surface hardening was also developed. Tribology tests have shown that the wear rates and friction coefficients of the coatings are highly dependent on the degree of filling of the gun.
