In most cases, electric motors and pumps break down due to depletion of loaded parts (shafts, bushings, etc.) after their contact with the rubber-metal bearings and liquid, flowing through the elements of electrical pump. Most of these items are made of expensive-standing steel ? 40X13 and 12X18H10T. The article discovers the questions of the process of hardening of steel parts with 45-combined hardening, consisting in coating of chromium with ultra-diamonds, subsequent turning and burnishing of the surface with diamonds. The paper also contains the results of comparative study of the mechanical surface treatment of 45-steel parts, 12X18H10T and 40X13.
