Plasma Reinforcement of Working Surfaces of Parts of a Deep Well Pump

Abstract

The possibility of using nitrogen-containing plasma that forms in a high-frequency charge is shown for the first time, and the plasma effect on changes in the physical and chemical properties of the inner surface of the cylinder is tested. The properties are estimated in accordance with the ISO 14577 standard on a “Nanoskan-3D” device. It is revealed that the microhardness of a deep well pump cylinder treated in the plasma of a high-frequency charge increases by a factor of 2 to 2.5, while the elasticity modulus becomes 25 to 40% larger.
