Berezhnits'ka, Ya. Fedorovich, Yu. Sichov, I. Petranyuk] Summary: A combined method of surface strengthening has been devised for pump shafts, which involves producing compressive residual stresses in the surface by means of shot-blast working with the subsequent deposition of metallization and polymer coatings. When a pump rod has operated for three years in a borehole, the compressive residual stresses provided by the combined treatment are substantially redistributed and change sign. In such cases, there is a reduction in the resistance to corrosive fatigue failure. To improve the working life of pump shafts working in boreholes, repeat hardening is required periodically.
