Conducted analysis of choice of optimum geometry of discrete electromechanics treatment after the
criterion of minimization of remaining tensions in a superficial layer by a computer design. Analysis of the
stress - deformed state of the surface layer by coating the surface of a discrete - hardened zones
electromechanical treatment of various geometrical parameters showed that the criterion of minimizing the
residual stress is the most optimal cross-hardened profile, which occupies 54% of the entire bearing surface
