The eﬃciency of agricultural machine and tool operation is noted to significantly depend on the characteristics of the working bodies. The paper emphasizes the importance of working bodies’ reliability and operating lifetime which largely depend on wear resistance, strength, as well as design features. (Research purpose) To substantiate the choice of eﬀective modern directions to increase the operating lifetime of wearable agricultural machine working bodies, the choice of types and characteristics of the materials used and technological methods for their hardening. (Materials and methods) The many years’ experience of the FNAC VIM in this area has been studied. A concept analysis of the relevant technical information has been conducted. (Results and discussion) The basics and conditions of abrasive wear of agricultural machinery parts are presented. The concept of "structural wear resistance" is clarified. The paper analyzes the materials (steels, hard alloys) of the working bodies of the agricultural machines used in Russia and abroad. Their main comparative physical and mechanical characteristics are pointed out. A method is proposed for selecting basic design parameters based on the strength characteristics of the materials used. Surfacing technologies for hardening the agricultural machine working bodies are compared. The paper substantiates the most eﬀective technological options, individual technical and economic parameters, recommendations for the use of materials. (Conclusions) It is proved that the use of surfacing technologies leads to a 1.5-4.5-times increase in the operating lifetime of working bodies and significant economic eﬃciency.

The most important task in designing competitive agricultural machinery is the production of parts with long service life. The development of new technologies and materials determines the technical level of agricultural engineering. The plowshare blade is the most loaded and important part, as its parameters determine the quality, energy and economic indicators of the technological operation of plowing. (Research purpose) To determine and confi rm theoretically material and technological parameters of low quality level of domestic plowshares manufactured without the use of modern technologies. Then they analyze construction materials of plowshares and other parts of tillage implements produced by leading foreign companies, and come to a conclusion that lowand medium-carbon boron-containing alloyed and high-alloyed steels are used in their production. Leading global manufacturers of machine parts also often apply surface hardfacing with carbide coatings. (Results and discussion) The authors have theoretically and experimentally determined the directions of increasing the strength and durability of plowshare working tools. They have chosen basic materials for plowshares basing mainly on the strength parameters. They have conducted comparative laboratory tests of various materials and witness samples (including double-layer ones) for abrasive wear resistance on two bench installations; identifi ed materials for carbide coatings, clarifi ed the relative wear resistance coeffi cients of steel carbide layers recommended for use in the design of plowshares; and considered a technological method of hardening machine working tools. (Conclusions) The authors propose a simplifi ed computational procedure for selecting design and material parameters (thickness and width of hardening coatings) of plowshare blades and over-chisels, depending on the wear characteristics of the materials used and the plowshare thickness. They have stated mathematical relationships that determine the linear wear of plowshare blades and chisels depending on the characteristics of the materials used, design parameters, soil conditions and total operation time and carried out comparative operational and duration testing of newly developed plowshares. It has been shown that the marginal operating time of new products exceeds the duration indicators of serial counterparts in diff erent soil and climatic conditions in 3.5-5.5 times.
