Wear resistance of cast Fe–Cr–C steels with various combinations of structural constituents at high velocities of sliding

Аннотация

The positive effect of the additional alloying of cast Fe–Cr–C steels on the formation of a secondary structure in the steels and their tribological characteristics under boundary friction has been shown. This effect leads to a decrease in the wear rate of the cast steel 1.2–5.2 times compared to that of the commercial 95Kh18 steel depending on the alloying system of the steels.
