This article presents a comprehensive analysis of modern methods and technological solutions aimed at increasing the wear resistance of steel components and parts of agricultural machinery. The relevance of this topic stems from the extreme operating conditions of machinery and tractors, which are characterized by the combined effects of abrasive wear (due to contact with soil and plant debris), impact and cyclic mechanical loads, and intense corrosion caused by aggressive environments (mineral fertilizers, pesticides, and moisture). The authors provide a detailed analysis of key protective coating technologies used in agricultural machinery manufacturing and repair. They examine both classical methods (electric arc cladding, thermal spraying) and precision technologies, including laser cladding and high-energy CVD (chemical vapor deposition) and PVD (physical vapor deposition), which enable the formation of layers with unique structures. Particular attention is paid to innovative approaches, such as the use of nanocomposite materials to increase the hardness and toughness of the surface layer, and the development of hybrid coatings that combine the advantages of ceramic and metallic components. The paper examines the practical implementation of these methods, their environmental safety compared to traditional galvanic processes, and their cost-effectiveness, resulting in increased service life for expensive components and reduced equipment downtime during fieldwork. Data is presented on the successful experience of the chair for Technical Mechanics and Specialized Machines in implementing practical research on the stated topic under a grant from the Kuban Science Foundation. A conclusion is drawn regarding the potential of using multilayer structures and self-fluxing alloys as an optimal balance between restoration costs and operational reliability.
The study was carried out with the financial support of the Kuban Science Foundation within the framework of scientific project No. H-25.1/36.
