Thermomechanical treatment of case-hardened 18KhGT steel
The high temperature thermomechanical surface treatment improved the wear resistance of case-hardened 18KhGT steel by 40–60% compared with ordinary heat treatment.
Increase of wear resistance of steel after TMST is caused by changes in the fine structure of steel which improve the contact resistance of microvolumes to plastic strain.
