“…The thickness of the hardened coating during pure vanadizing was 5-19 μm on steel [8,12] and 25-35 μm on cast iron [33,34]. At a low concentration of aluminium Al in the reaction powder medium (up to 1.5-2%), the thickness of the hardened layer increased to 35-55 μm.…”

“…The regressive relationship between the coating thickness h and the concentration of aluminium Al and inert filler in the reaction powder medium was obtained on the basis of experimental data (Figure 3). The thickness of the hardened coating during pure vanadizing was 5–19 µm on steel [8,12] and 25–35 µm on cast iron [33,34]. At a low concentration of aluminium Al in the reaction powder medium (up to 1.5–2%), the thickness of the hardened layer increased to 35–55 µm.…”

Creating hardening coatings through thermo-reactive diffusion is an effective method for increasing the service life of cast iron parts. The influence of aluminium on the process of thermo-reactive diffusion of cast irons with vanadium has been studied. It has been found that the concentration of aluminium in the reaction powder medium affects the structure, thickness, and hardness of the coating. The most optimal concentration of aluminium is 0.5–2.5%. This concentration makes it possible to increase the thickness of the hardened coating by 1.5 times with a decrease in microhardness by 10–25% compared to pure vanadization.

“…To evaluate the mutual slip of tooth profiles, the concept of specific slip is used (Kobeleva and Tyktamishev, 2017). The sliding speeds of the gear and wheel, which are in conjugation, are determined (Veselovsky et al, 2022b) as:…”

The paper presents data on the resource and wear of the gears of agricultural tractor transmissions, on the basis of which the research problem and the novelty of the proposed methodology are formulated, based on the development and application of the stress state model of the gear, taking into account surface hardening. The methodology and calculation scheme for determining the power parameters of gearing are described in detail. In this case, the dependences and results of previous studies in the field of increasing the durability and reducing the wear of gears of transmission elements of vehicles of various functional purposes were used. To achieve this goal, the mathematical models of the stress state of gears are constructed without the presence of an external diffusion hardening coating and with a coating. Based on the simulation of the process of interaction of rubbing pairs of gears, the distribution of stresses in the contact zone over the surface layer of non-hardened and cemented to a depth of 1 mm gears, as well as the dependence of deflection on the thickness of the cemented layer and the deformation of the cemented layer during operation was established. Considering the research results given in literature, as well as those obtained on the basis of our own research, it should be noted that the analysis of gear stress state is an important direction in the study of the durability of gear units, the entire gearbox, and other gears of tractor transmissions and automotive technology at the present time. At the same time, the actual task is to establish the ratios of the allowable wear of gears and the limiting value of displacement of the centre distance, taking into account changes in the stress state scheme when using various types of coatings.
