Extremely low operating temperatures and difficult mining and geological conditions for open mining of diamonds, gold, coal by industrial organizations require large-scale earthmoving works, which requires significant material costs for the purchase and supply of working bodies of various mining equipment, such as bulldozer ripper crowns, teeth and bucket tips for excavators and loaders. Currently, these working bodies of mining equipment are 90% produced and purchased from foreign companies. But the difficult global situation associated with the imposition of sanctions on the supply of spare parts for imported equipment requires the development of new scientific solutions for the creation of import-substituting technologies for the production of working bodies of mining machinery. Therefore, scientific research of the service properties of materials of the working bodies of mining machinery of imported manufacturers, is also a necessary factor for the accelerated development of import-substituting technologies.
