Abstract:  
To prolong the life of gear wheel made of chrom-nickel steels, they are subjected to complex treatment to increase their strength including thermochemical treatment and plastic surface deformation. Cold plastic deformation substantially changes the structue of the phases of the case, and this has a certain effect on the qualitative characteristics of the surface layer as well as on the most important operational characteristic of gear wheels...
