Conclusions

  1. 1.

    The wear resistance is highest for alloys with both chromium and titanium. The optimal amount of carbon depends on the titanium content. It should be above stoichiometric.

  2. 2.

    The wear resistance of high-carbon Cr−Ti alloys depends on the structural condition of the matrix and the total quantity and type of the carbide phase.

  3. 3.

    The abrasive wear resistance is highest for alloys U20Kh6T4M and U25Kh6T4M with a structure of austenite-carbide or austenite-martensite-carbide, with at least 30% retained austenite. The best results are obtained when the carbide phase is the strong and hard TiC, in combination with carbides M7C3 and M23C6.
