This paper presents experimental studies of the influence of surface plastic deformation (SPD) (roller burnishing) on the properties of the surface layer of a part “guide apparatus” of the centrifugal submersible pump for oil production. The parts made of composite powder alloys based on the iron-copper system were taken as an object of researches. The microstructure of the surface layer of the samples, surface roughness, microhardness, and hardness were studied. Testing of the samples for the surface layer resistance to abrasive wear according to the Calotest method showed a decrease in the wear intensity by 1.5–1.6 times in comparison to samples without SPD.

Application of roller burnishing technologies to improve the wear resistance of submerged pump parts made of powder alloys
