Abstract

A turbine engine component has a first portion and a hotspot portion with both portions being substantially covered with a thermal barrier coating (TBC). The hotspot portion may be additively manufactured to the first portion. Furthermore, the hotspot portion may have a single crystal microstructure to resist high temperatures and the first portion may not have such a microstructure and may further be cast. A method of forming the component includes the steps of casting the first portion and additively manufacturing the hotspot portion to the first portion, then covering the first and hotspot portion with the TBC.
