Abstract
As a result of poor quality, parts of tillage equipment have to be replaced 3-7 times a year. One of the reasons is the lack of attention to the possibility of using technical ceramics in agricultural engineering to improve the wear resistance and durability of machine parts. (Research purpose) The research purpose is in assessing the state of research and prospects for the use of ceramic materials in the Russian Federation for the needs of the agro- industrial complex. (Materials and methods) For the experiments has been used nanostructured boehmite obtained by hydrothermal synthesis to improve the properties of materials and coatings. The crack resistance was determined by the indentation method, and the methane content in the biogas was determined by the chromatographic method. (Results and discussion) The article presents the results of the use of aluminum oxide ceramics for the manufacture of parts of tillage equipment, which allows increasing the resource of parts for processing loamy soils by 2.4-4.5 times. The creation of nanocomposites is promising to increase the strength, wear resistance and crack resistance of the material. In the composition of the non-stick coating, the addition of boehmite increases the abrasion strength of the coating and the compressive strength of the samples by 2.2-2.7 times, and improves the quality of casting. The use of highly porous ceramic materials in the gating system helps to reduce waste, reduce production costs, and improve the quality of foundry products. (Conclusions) Ceramic materials due to their high hardness, wear resistance and corrosion resistance are becoming promising for use in the agro-industrial complex. The widespread use of modern ceramic materials as parts of tillage equipment, non-stick coatings and for the filtration of melts will improve the quality of casting, the durability of products, and reduce the cost of their production. Positive results on wastewater treatment with the use of highly porous ceramics allow us to consider it an innovative material for such purposes and it is advisable to continue research in this direction.
