A methods is proposed for modeling the stress-deformed state of low-plastic material surface layer, using the example of SCH20 cast iron, processed by deforming broaching. From the standpoint of the plasticity resource exhaustion, the analysis of the surface layer was carried out, which made it possible to establish the presence of plastic deformation local zone. The possibility of using a combined technology, including the operations of deforming broaching and finishing antifriction non-abrasive treatment, taking into account the influence of local plastic deformation zone, has been established.
