Improving the performance properties of gears for mining equipment

Deformation hardening ‐ important technological factor of management of carburized layer substructure. The formation of a favorable substructure ‐ substructure with high resistance to local microplastic deformation ‐ occurs in conditions of development of competitive processes. On a degree of their development is renders the influence of initial structural condition of a carburized layer, which, except chemical composition, is defined by technology of thermochemical treatment. To number of the factors, dependent from technology of thermochemical treatment, concern: carbon saturation in the carburized layer, the martensite morphology and carbon concentration in it, volumetric share of a redundant carbide phase and its distribution in a carburized layer.
