Intensive soil compaction, which is caused by the use of modern powerful tractors with high weight and the presence of higher working speeds, and as a result reduces the service life of tillage equipment. Difficult weather conditions cause an increase in the load on the working bodies of tillage machines, with the wear of the surfaces of the working bodies of agricultural units. The article considers the problem of increasing the resource of the working bodies of tillage machines due to the application of wear-resistant coatings. The types of wear and the influence of abrasive materials on the working bodies of tillage machines are analyzed. Determined optimal materials and methods to increase the wear resistance of the working bodies of tillage machines. Features of formation of a metallization covering which is reflected in its structure and character of defects which can differ in the sizes, density, morphology and orientation are considered. The dependence of the properties of coatings on the material doping system is substantiated. Equipment and materials for coating are given. Taking into account the received information, conclusions are made and the analysis of technology of drawing wear-resistant coverings for increase of a resource of working bodies of tillage machines is carried out.
