Conclusions
-
1.
The influence of abrasive particles under high pressures causes phase transformations (martensitic) in the working surface of unstable austenitic steels.
-
2.
The intensity of the martensitic transformation depends on the nature of the solid solution.
-
3.
Unstable austenitic chromium steels tend to greater hardening of the surface layer and are more resistant to abrasive wear than stable chromium-nickel and chromium-manganese steels, which are hardened only by plastic deformation.
-
4.
The wear resistance and hardening of unstable austenitic steels depend on the completeness of the martensitic transformation and on the properties of thea phase formed during wear.
