During the operation of surfaces in ship propeller shafts they are worn out intensively. To prolong their life there are used at shipyards an automatic surfacing under flux (ASF) which, besides high efficiency is characterized with a considerable share of a basic metal participation in surfacing worsening properties of a deposited layer. The aim of the paper consists in the technology improvement of ship propeller shafts restoration with the aid of ASF and SBM decrease on the basis of complex mechanization and energization of a technological process. The process energization consists in the transfer character control of electrode metal through an arc by geometry and properties of driven rollers at the expense high-frequency extra-axial oscillations of an electrode (EOE) created by a special mechanical generator. The developed ASF technology ensures pad quality meeting requirements of the Register.
