“…To substantially (by a factor of 2.8 to 3.3) increase the wear resistance [8] compared with high-strength boron-containing steels (30MnB5, B1500, B1700), it is necessary to add up to 25-35% of superhard cast tungsten carbide WC to powder alloyed iron-carbon hard alloys. Tests demonstrated that adding much WC causes excessive embrittlement of alloys (especially if the layer thickness > 2.5 mm) and reduction in their cohesive and adhesive characteristics [14,15]. For full-scale field studies and tests, prototype tools were made of 30KhGSA steel and B1500 and B1700 boron-containing steels.…”

Issues related to the study of wear resistance, strength, and other material characteristics of parts of tillage machinery are addressed. The importance of improving the heavy-duty tool of domestic tillage machines is evaluated. Chemical compositions and mechanical properties of steels for tools of agricultural machines of leading European manufacturers are given. New grades of steel for high-strength rolled products have been developed.Comparative results of laboratory bench tests for wear resistance of commercial and prototype domestic and foreign grades of rolled steel and powder hard-alloy coatings are presented. An effective technology for hard-facing of wearable parts of tillage machinery is substantiated and analyzed. Verification comparison performance and life-cycle tests of tools manufactured using new materials and facing technology were carried out. The life of the prototype tools was increased by a factor of 2.8 to 3.8. The market potential of using new materials science and technology developments in Russian agricultural production is assessed.

“…Hardfacing layer thickness ranges from 2 mm to 3 mm with many passes [53]. [54] applied hard alloy coatings on the working parts of agricultural machinery as hard surface against soil abrasion wear against working parts and these coating layers reduced the wear rate and mention that this method is very effective for agricultural machinery.…”

GRICULTURAL production is a world spearhead to face hungry crisis and the main part of this facing is agricultural machinery. Agricultural machinery exposed to failure due to wear and corrosion. This leads to a decreasing lifetime of working parts of agricultural machinery. Agricultural machinery contain seedbed preparation machinery, planting machinery, service and protection machinery, harvesting machinery and post-harvest machinery all types of agricultural machinery deals with different soil condition (soil moistures and soil types), plants (different stem diameter, cutting heights and plants moisture), and agricultural chemical (pesticides and chemical fertilizer). There are many studies searching the optimum method to increase the wear resistance of working parts of agricultural machinery. These methods contain the improvement the new material, hardfacing allying, surface coating, and nanocomposite coating. Nanocomposite coating is a new trend to promote surface properties of the different metal used in manufacturing agricultural machinery. This new trend use nanoparticles as reinforcement in the metal matrix and incorporation process lead to super hardness coating with low corrosion rate and low wear rate compared to conventional surface coating materials.

“…Therefore, in abrasion areas sometimes light and corrosion-resistant polymers [ 10 ] or aluminum alloys are used, even when foamed [ 11 ], but where the presence of mass and strength is essential (e.g., tillage and cultivators), the use of different steels is preferred. Generally, alloyed martensitic steels are utilized in these applications, often with hard alloy coatings to aid the wear resistance [ 12 ].…”

The wear behaviour of two martensitic and one multiphase steel targeted for abrasion and erosion applications in agriculture and mining industry were investigated in three abrasive test systems with different complexity. Scratch tests were performed with different indenter radii, shapes, and loads. The material behaviour was also investigated in multi-asperity contact systems. Pin-on-disc tests were performed with various loads and abrasive particles, as well as abrasive slurry-pot tests with different sliding velocities, distances, and impact angles of the abrasive media were performed. Comparing the test systems, the tested materials ranked similarly based on their wear performance, however, in each configuration, the dominant variable of the wear mechanism differed. The significance and contributions of test paramecenterters, the material’s mechanical properties (H, , , E, , , W, , ) and the dimensionless numbers formed from them were investigated on the wear behaviour and the surface deformation. Correlation between parameters was established by multiple linear regression models. The sensitivity of the tested materials to abrasion was evaluated taking into account the wide range of influencing parameters.
