PROTECTION OF STEAM TURBINE BLADES AGAINST STEAM DROP EROSION Russian patent published in 2015 - IPC B23K26/342 C23C26/00

Abstract RU 2545878 C2

FIELD: process engineering.

SUBSTANCE: invention relates to protection of steam turbine blades against erosion. Proposed process comprises application of protective coating on the blade. Coating is applied by laser surfacing. Laser head is displaced at the rate of linear interpolation V_i not over 0.05 m/s at laser radiation power making 800-1200 W.

EFFECT: hardened ply of 1/3 length of the blade root at sufficient aerodynamics.
