摘要

PROBLEM TO BE SOLVED: To carry out in-line surface treatment for scratch prevention which is incorporated in a production line of compressor blades for a gas-turbine engine. SOLUTION: A coating (6) of a comparatively soft metal is applied by electrical discharge surface treatment at a part (5) undergoing a specific pressure from a disc (7) in an implantation part (4) of the blade (1) to be implanted in a disc (7) of the compressor of the gas turbine.
