Application of higheffective rehabilitation technologies at renewal of gas-turbine engine blades from alloyed steels

Abstract

The wear of gas-turbine engine blades, arising up in the exploitation, requires their premature replacement or restoration repair. Thus repair is more rational and economic justified decision. Questions are examined in the article, related to research and development of new technology of repair of blades from  alloyed steels, including a few variants of welding processes.
