Abstract
PURPOSE: To improve the erosion resistance of a turbine blade and permit the manufacture of a large sized turbine, by flame spray coating a layer of Ni-Cr-B onto a point end leading edge part of the turbine blade made of titanium system alloy.
CONSTITUTION: To the point end leading edge part of a turbine blade made of titanium system alloy, a flame spray coating consisting of 60W80% Ni, 15W30% Cr, 5% B and the rest of Fe, Si is applied. Further in the atmosphere of vacuum or inactive gas, heat treatment is applied to provide a diffusion layer in the blade end leading edge part. In this way, wear resistance and erosion resistance of the turbine blade can be improved to obtain the extension of a life. While use of the titanium alloy can form the blade in large length to permit the manufacture of a large sized of the turbine.
