Abstract

PURPOSE: To prevent the erosion due to drain and the stress corrosion cracking of turbine blade, by flame hardening the surface of an erosion-preventive layer of a turbine blade, then by tempering said surface at a specific temp., and by shot peening it.
CONSTITUTION: Erosion-preventive layer 13 in the range of L2 length from the steam inlet side top end, which is liable to be eroded by drain, of a turbine blade 7 is flame hardened at 1,000W1,600°C temp. using a heating burner A. Then it is tempered at 500W600°C temp. for about 3hr for the purpose of the regulation of hardness and uniformalization of the distribution of carbide. The erosion-preventive layer has 600W700 Vickers hardness. Finally compressive stress is given to the surface by shot peening.
