ABSTRACT:
A rotor blade is manufactured by making a soft alloy into a blade body with a curved section, joining a hard alloy to the leading edge of the blade body, coating the back side surfaces of the leading and trailing edge portions of the blade by alternately giving at least one coat each of a Ni-Cr-B-Si alloy and WC by spraying and fusing the coats onto the backing surfaces, and then coating the entire front side surface of the blade in the same way.
