FIELD: excavator structural elements.
SUBSTANCE: invention relates to structural elements of excavators and other earth-moving machines. As a result of intense high-temperature plastic deformation in combination with rapid cooling, the metal of the lower half of the tooth, which is subject to the greatest wear, receives an increased intensity of plastic deformation, which remains during cooling and hardening, which ensures that this half of the tooth is given wear resistance that exceeds the wear resistance of the upper half, as a result of which both halves of the tooth during operation, they will wear out at the same speeds with the tooth retaining its original shape, i.e. the effect of self-sharpening of the tooth will be provided.
EFFECT: increasing the wear resistance of the tooth and reducing energy consumption for rock excavation.
