“…At the same time, thermomechanical treatment is applied rather rarely in mining mechanical engineering. Influence of thermomechanical treatment on wear resistance of materials is studied insufficiently [13][14][15][16][17][18] and there is almost no data about its effects on abrasion wear resistance. Therefore, researches of the influence of thermomechanical treatment on abrasion wear intensity are important and topical task.…”

This work presents results of experimental researches of influence of various high-temperature 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.
