COMPONENT FOR A TURBOMACHINE AND METHOD FOR MANUFACTURING SUCH A COMPONENT

摘要

The invention relates to a component for a turbomachine, in particular a gas turbine, or another engine containing a hot component, which component (14) is prone to crack formation and propagation by being subjected to high temperatures and/or a corrosive and/or oxidising atmosphere and/or a high mechanical load and/or cyclic thermal load and/or transient conditions, whereby said component (14) contains at least one base material (15). A substantial extension of the component lifetime is achieved by providing said at least one base material (15) with a self healing system in form of an added active phase (16), whereby said active phase (16) comprises a melting point depressant and/or a substance or substances with a softening or melting point below or within the range of the operating temperature of the component (14).
