Results are provided for a study of the effect of different forms of ultrasonic treatment on properties of powder corrosion-resistant steel PH-1 prepared layer-by-layer with selective laser melting. Specimens are studied after ultrasonic cavitation-erosion and cavitation-abrasion treatment, and also ultrasonic surface-plastic deformation. After treatment microhardness and parameters of the micro- and sub-microgeometry of a surface layer are measured. Fields of application for this form of treatment are considered.
