“…Given the geometric dimensions of the chamber, steel samples for testing were made with a size of 60 × 70 × 2 mm [18]. Before applying the studied conservative materials [19], they were marked [20]. Preservative materials were applied to the prepared samples by immersion and kept for 24 hours at room temperature [21], then placed in a humidity chamber H-4 [22].…”

The solution of universal, global problems of energy and resource conservation in both mechanical engineering and agro-industrial complex are inextricably linked with the solution of issues of protection of machinery from corrosion. Modern agricultural machinery, and self-propelled combine harvesters in particular, are operated periodically for one or two seasons a year. Most combine harvesters are stored in the open areas of agro-industrial enterprises, and it is exposed to aggressive environmental influences (fluctuations in temperature, humidity, wind, solar radiation, dust and others). The main type of environmental impact on the equipment is atmospheric corrosion and the corrosion wear caused by materials, parts and components, which leads to its premature failure. Thus, the fatigue strength of steel products when stored for 12 months in the open reduces by 28–58%. To ensure temporary corrosion protection of combine harvesters, a large number of conservation and working-conservation oils are used. However, the unresolved number of issues of theoretical and practical nature leads to the unjustified use of protective equipment, which either does not provide the required duration of storage of equipment, or increase the cost of its preservation. Standardized methods of testing anti-corrosion lubricants in the vast majority have a number of disadvantages, the most important of which is that the evaluation of protective properties is carried out in units that do not allow to estimate their service life, but only show the corrosion of the metal.

In the current conditions, there is a multifaceted urgent problem of meeting the growing demand of agriculture for modern and high-quality equipment. Mulchers for tractors, excavators and skid steer loaders are becoming more and more popular as a type of attachment. Carbide cutting elements for the mulcher have a high resource, do not require sharpening, and are not afraid of small stones in the soil. An urgent task in terms of import substitution is the organization of their production at domestic engineering enterprises, which requires information on the materials used for manufacturing. The purpose of the study is to study the details of working bodies for foreign-made mulchers and to identify domestic analogues for the organization of industrial production in the Russian Federation. Hardness of foreign-made mulcher base is 431…710 HRC; cleaner - 221; carbide plate - 1068 ... 1073; carbide crown - 1062 ... 1076, tool holder - 51 HRC. For the production of working bodies of mulchers, Russian analogues of structural materials can be used. The tool holder and base can be made of steel for castings of ordinary grades 40KhL or 35GL GOST 977-88. For the manufacture of a scraper, chromium steel grade 40X or manganese steel grade 35GL is suitable. Parts should be subjected to a heat treatment consisting of quenching and low stress relief tempering. For the manufacture of hard-alloy elements of cutters, it is advisable to use tungsten sintered alloys of grades VK8 or VK10. Hard alloy elements should be soldered with solder grades LNMts 49-9-0.2, MNMts 55-6-4 or MNMts 9-23.5, which provide high strength of steel-hard alloy joints of 350 ... 450 MPa. It is advisable to weld the scraper to the base as follows. First, the root welds are welded with Sv-08G2S solid section welding wire by semi-automatic gas welding. Then the welded joint is surface hardened with Kiswel K-700HT or WELTEK-H565 flux-cored wire by semi-automatic gas welding. This technology provides a weld with a hardness of 54…60 HRC.
