In agrarian production one of the most common technological operations is cutting of soil or plants. It makes up at least 70% of the total volume of mechanized works. The purpose of this study is to help maintain the agrotechnical parameters of the cultivator's blade by coating the blade with powder wear-resistant coatings using the one-sided gas-flame surfacing technology. The technology of strengthening the cultivator blade using one-sided gas-flame surfacing is applied. The technology of one-sided gas-flame surfacing guarantees an even reinforcing layer of the cultivator blade with a width of 10-12 mm and a layer thickness of 0.2 mm. With the development of gasometric spraying methods it is possible to atomize various materials such as polymers, carbides, metals. These coatings withstand the impact of high thermal loads, shock-abrasive and chemically active environments. Therefore, the addition of chromium carbide powder PG-12N-02 has a positive effect on the properties of the coating. It increases the durability and wear resistance of the cultivator blades. A saw-tooth blade is formed. Comparison of application methods mentioned above shows that the quality of coatings expressed in the parameters: adhesions, porosity, oxidation levels remain at approximately the same level. However, a comparative analysis of foreign practice has shown that the method of gas-flame surfacing is more technological, more productivity, and the specific costs of the coating are reduced.
