The experimental studies results of the mechanical and thermo-mechanical treatment influence of wear resistance of excavator bucket tooth materials and rotary cutting tool are presented in this article. Experiments on abrasion in different rocks were investigated. In the example of 110G13L steel (Hadfield steel), it was shown that mechanical strengthening (cold hardening) is an effective way to improve wear resistance of machine parts working in abrasive environments. It was revealed that if the hardness of abrasive materials is lower than the hardness of cold hardening steel, wear resistance may increase by 10 times and if the hardness of abrasive materials is higher than the hardness of steel with cold hardening, it does not influence wear resistance. It was found that the high-temperature thermo-mechanical treatment of 30KhGSA steel increases its hardness (by 23%) and wear resistance (by 38%) by comparing with the same steel after hardening. It was concluded that the advisable use one of these methods depends on rock hardness.

This work presents results of experimental researches of influence of various hightemperature thermomechanical treatment (HTMT) modes in 35KhGSA steel – material applied in rock-destroying cutters – on hardness and wear rate for the most common abrasive rock in mining operations – sandstone. It has been found out that HTMT leads to increase of steel hardness and reduction of wear rate compared to heat treatment applied at manufacture of cutters. The maximal increase of hardness (by 23%) and reduction of wear rate (by 38%) corresponds to the mode of distortion accumulation of ∼1,5 at 900 °С at water quenching and tempering at 230 °C. A conclusion that thermomechanical treatment is an effective way to increase the wear resistance of steels applied in the conditions of abrasion wear has been drawn.
