The paper presents data on the parameters that determine the quality of the surface layer of the pump plunger, such as roughness and hardness. The results of the study of the quality of the surface layer of the pump plunger, after turning with a blade tool and after ultrasonic hardening and finishing processing, are presented. Analysis of the obtained results of the state of the surface layer shows a significant decrease in roughness and an increase in the surface hardness of the plunger as a result of ultrasonic hardening and finishing processing, which contributes to an increase in the service life of the part.
