FIELD: machine building.
SUBSTANCE: proposed method consists in securing strip on vane leading edges, all along their length, said strip being made up of separate shaped stellite plates cut from solid shaped casting and butted together. One-piece stellite casting is divided into two or more sections. Said plates cut from one ingot section are arranged sequentially from vane apex starting from plates from mould closest to periphery. Plate face closest to mould periphery is arranged on vane apex side.
EFFECT: higher reliability due to longer life of anti-erosion protection.
