“…However, these signs of wear products are insufficient to reconstruct the surface of the gear teeth, and the accuracy of this method may also be affected by deformation of wear products, accumulation of foreign particles, contamination, etc. [10][11][12].…”

“…As a result of this process, a layer with very good properties can be obtained, such as high microhardness, good wear resistance and corrosion resistance [11][12][13][14]. Due to the needle-like microstructure, the borated layer is characterized by good adhesion to the steel substrate.…”

“…However, despite these numerous advantages, borated layers are quite fragile. This disadvantage can manifest itself in the form of chips and peeling from the substrate [11]. At the same time, there are many methods to increase the strength and stability of such layers [15][16][17][18].…”

The conducted research is devoted to the analysis of the wear resistance of materials used in reinforcing coatings of working bodies of agricultural machines subjected to friction under abrasive action in soil conditions. The aim of the study was to determine the degree of wear of the hardened teeth of the disc under the load of their impact on the soil in real operating conditions. The disk of a toothed harrow, which is a hardened working body of agricultural machinery, was used as an object of research. The individual teeth of this disc were the test samples. To increase the wear resistance of the teeth, a variety of reinforcing coatings were applied. The results of the study made it possible to comparatively evaluate the effectiveness of various reinforcing coatings and identify their effect on the wear resistance of the teeth of the disc. This study provides important data for further improvement of materials and technologies in agricultural engineering in order to increase the durability and efficiency of working bodies.

“…Compared with ordinary grinding wheels, the bionic grinding wheel has higher utilization of cutting fluid, smaller grinding specific energy, and surface roughness, which provides a new theoretical basis and technical guidance for the development and application of green grinding technology. Babitsky et al [14] applied the shape of the rhinoceros beetle's claw toe to the design of tillage ring-cutting roller cutter teeth, the shape of the mayfly's forearm to the design of spring-loaded soil leveler cutter teeth, and the head features of the golden tortoise to the design of stubble mower tools. They found experimentally that the three tools could reduce working resistance.…”

Along with the transformation and upgrading of the manufacturing industry and the arrival of the industrial revolution, the structure of parts is becoming more and more complex, the variety of materials, the demand for cutting performance of tools is increasingly diversified, and the design and development of tools are facing many challenges. By studying the cutting phenomena in nature, scholars have discovered that the teeth and claws, etc., of living organisms have unique structural characteristics, the design and development of tools that mimic the structural features of living organisms have become a new research direction. In order to solve the problem of high energy consumption in the cutting process and to reduce the resistance of the cutting process, five bionic cutting tools were designed based on preparation and geometric feature extraction of limpet teeth and applying them to the design of the tool structure, using the cutting force as the cutting performance index, and exploring the cutting performance of the bionic tools by comparing them with ordinary tools. The cutting force analysis revealed that the No. 2 bionic tool had a significant force-saving effect, with a 16.2% reduction in cutting force. The effect of cutting parameters on the No. 2 bionic tool was investigated through single-factor experiments. The results show that a limpet bionic cutting tool with appropriate dimensional parameters has a significant force-saving effect and improves the tool's cutting performance.

Using the method of calculus of variations, the task was set to determine the shape of the paw profile of a plane-cutting cultivator with minimal traction resistance. Based on this functional, the Ritz differential equation was compiled, which makes it possible to find the value of the functional by possible linear combinations of selected functions with constant coefficients composed of the first terms of the sequence, as a result of which an expression describing the required profile of the working organ was obtained. The Ritz differential equation made it possible to determine a family of extremals for a given functional: the desired curve belongs to this family and satisfies the boundary conditions of the problem. Using the finite element method, the three-dimensional problem of substantiating the profile of the tillage working body was solved. As the results of experimental studies have shown, a working organ with a reasonable profile has a lower energy consumption by 15-35% compared to traditional ones, while reducing the ridge of the soil surface along the width of the treatment.
