“…On the other hand, the existence of oxidised layer could postpone the wear of the specimen by reducing real contact between the counterpart ball and the surface of the coating. 25 The SEM images in Fig. 3 show that the worn surface of the AC-HVAF coating can form a more complete and higher fraction of oxidised tribolayer than that of the HVOF coating under the same test conditions, resulting in the more superior wear resistance of the AC-HVAF coating.…”

“…Based on the above analysis, it can be summarised that the formation of a oxide layer could be a significant factor in reducing the wear loss because it acts as a protective layer. 25 The slightly oxidised tribolayer has higher hardness than the coating matrix, which can strengthen the dense structure of the coating. On the other hand, the existence of oxidised layer could postpone the wear of the specimen by reducing real contact between the counterpart ball and the surface of the coating.…”

“…It has been confirmed that higher surface roughness, that is more contact spaces between the sliding surfaces, could lead to a higher chance of oxidation and higher wear losses. 25,29 Meanwhile, the HVOF coating has more defective regions where the oxygen preferentially diffuses along due to the high atomic activity of these regions, resulting in more serious oxidation on the surface of the HVOF coating. According to the previous discussion, the protective effect of the tribolayer decreases as the oxidation becomes serious, and eventually peels off from the coating surface.…”

amorphous coatings have been prepared by the activated combustion high velocity air fuel (AC-HVAF) and high velocity oxygen fuel (HVOF) processes. The microstructure and wear resistance of the amorphous coatings are comparatively studied. The wear volume loss of the AC-HVAF coating is approximately seven times less than that of the HVOF coating, indicating that the AC-HVAF coating exhibits better wear resistance. Detailed analysis on the worn surface indicates that the enhanced wear resistance of the AC-HVAF coating is mainly attributed to the formation of a more stable oxide tribolayer and smoother worn surface, which result from the dense and complete amorphous microstructure of the AC-HVAF coating. The wear mechanism of the amorphous coatings is dominated by oxidation wear.

“…Under industrial conditions, it is difficult to achieve satisfactory efficiency and productivity levels [3]. A desire to achieve greater process efficiency is the driving force behind the numerous studies accelerating process kinetics and process cost reduction [21,22]. The nitrided layer thickness depends on the conditions of conducted process, the properties of the material being nitride, and the reactions occurring on the material surface and the atom diffusion deep into material [23].…”

The aim of this study was to determine the impact of the heating rate of steel balls made of AISI 52100 alloy steel on the kinetics and efficiency of the gas nitriding process when carried out using a chemical reactor with precise thermo-gravimetric measurements, which allowed for changes in sample mass during heating and nitriding to be monitored with an accuracy of 50 µg. In the chemical reactor, the examined alloy steel was subjected to a heating process at the selected nitriding temperature of 590 °C. Two heating variants were used: the first variant relied on heating to the nitriding temperature with different rates—1 °C per minute, 2 °C per minute, 5 °C per minute and 10 °C per minute, respectively—whereas the second variant relied on the fast—25 °C per minute—heating of treated specimens to a temperature of 475 °C, at which, the nitrogenous potential of the atmosphere promotes faster nitrogen diffusion deep into the nitrided substrate, followed by reheating up to the nitriding temperature at different rates: 1 °C per minute, 2 °C per minute, 5 °C per minute, and 10 °C per minute, respectively. To evaluate the impact of heating rate kinetics and effectiveness during nitriding on the obtained surface layer quality, we investigated the phase composition, microhardness distribution, and thickness of the obtained diffusion layers. It was found that heating to a temperature of 475 °C in the nitriding process does not significantly affect the average mass gain of a sample. Above this temperature, within the range of nitriding temperatures, the extension of time increases the sample’s mass gain. Simultaneously, it was found that the use of a constant heating rate allows for thicker nitrided layers and a greater sample hardness to be obtained. Dual-stage heating, in turn, is more effective in the context of sample mass gain per time unit.

“…The method of production as casting or powder metallurgy and the composition of high-speed steel, which is subjected to duplex treatment, is critical. The optimal composition of the nitrided layer for different high-speed can be very different [40][41][42][43][44][45].…”

The paper presents a series of experimental results for assessing the effect of duplex vacuum-plasma processing as sequential ion nitriding and coating (Nb–Ti–Al–V) N on the characteristics of the surface layer and the wear rate of complex profile tools as herringbone broaches and gear-shaping cutters from high-speed steels powder during machining a heat-resistant nickel-based alloy. The rational duplex processing modes for each type of multi-profile cutting tool under investigation were established. Tests of the tool after duplex processing under conditions close to those encountered in production showed an increase in the operational durability of herringbone broaches and gear-shaping cutters up to two times in comparison with the original tool.
