Study of Methods Relating to Increase of Contact Pitting Resistance in 45, 40H, 35HGSA Steel due to Development of Heterogeneous Structure Involving Mechanical Hardening Technique

摘要

New static-pulse treatment method was offered to increase contact pitting resistance of machinery parts. This method forms cold-worked layer with high hardness located deep in the part. The static-pulse treatment method is characterized by important feature that helps to form various levels of hardening uniformity of the surface layer. For the first time undertaken studies provided recommendations relating to uniformity of surface layer mechanical hardening, which increases contact pitting resistance of machinery parts made of 45, 40H, 35HGSA steel.
