Document Type and Number:
Japanese Patent JP2714607
Kind Code:
B2
Abstract:
A rotating or moving metal component such as a blade for a gas turbine engine is made from a composite bar of titanium alloy (10, 20, 40) with the sides of the bar having a surface layer (11, 21, 41) of eg. nickel which is less likely to ignite in particle form when present in oxygen or air. After the surface layer has been bonded to the titanium alloy it is then parted to provide sections which extend perpendicularly to the plane of the surface layers. Each parted section (24) may then be machined into a blade with the nickel portion forming the tip of the blade. Alternatively, each parted section may itself form the blade tip by attachment on its titanium alloy side to a blade stem.
