Conclusions

  1. 1.

    Running in of steels with a bainitic structure with a high carbon content (0.8–1%) is accompanied by little wear.

     
  2. 2.

    In the process of running in the complex dimensionless characteristic of surface roughness Δ decreases.

     
  3. 3.

    The lower wear of the bainitic structure in the process of running in as compared with a martensitic structure is due to hardening of the surface layer, accompanied by an increase of microdistortion.
