Conclusions

  1. 1.

    The increase in the wear of steel 40Kh subjected to different heat treatments during friction in vacuum at 20 and −190° at given sliding speeds is associated with decreasing plasticity of the original structure.

  2. 2.

    The plasticity of the structure affects the wear resistance to the extent the structure is capable of forming and retaining a hard white layer on the friction surface.
