Development and implementation of procedures and equipment used in UF of outside and inside surfaces of bodies of rotation showed, that UF is quite easy and versatile. This process as well as regular mechanical burnishing provides for high operational characteristics of the parts processed with much less static force. The aim of the present study - to increase operation life of propellers by means of creation of hardened case of the surface and decrease the surface roughness, which to be effected without hand accurate grinding. As a result of SPS methods selection to obtain maximum hardening depth and highly smoothed surface ultrasound frequency SPS was preferred or the so-called hardening-cleaning processing. For investigation of UF influence on roughness and surface strength of materials, БрА9Ж4Н4 bronze and 0Х14НДЛ stainless steel samples were taken, which are used in fabrication of propellers.
