Customers have increased demands on reliability, operational efficiency and environmental friendliness of ships of the Arctic navigation. The propulsion systems of Arctic navigation ships, in particular icebreakers, consist of a powerful multi-­shaft powerplant with a unit capacity of 20 MW and more, and a short rigid shaft line with a minimum number of bearings. It is proposed to use the technology of powder laser deposition of bronze on a steel sleeve for forming an antifriction friction surface.
