Metal Science and Heat Treatment Aims and scope

Conclusions

To harden the surface of parts made of KCh 35-10 malleable iron operating at temperatures up to 300° one can recommend laser heat treatment. The use of laser hardening for differential gears at AZLK has produced savings of 303,000 rubles.
