Manufacturing method of hot gas component path involves processing portion of structural coating surface so as to deform structural coating in vicinity of respective top groove, such that gap across groove top is reduced

摘要

The manufacturing method involves forming grooves (132) in a gas component path that is provided with a substrate (110) comprising an outer surface (112). The grooves are provided with a base (134) and a top (146) which extends along the substrate. A structural coating (54) is applied on a portion of the substrate. A portion of a structural coating surface is processed so as to deform the structural coating in a vicinity of a respective top groove, such that a gap across the groove top is reduced. An independent claim is included for a hot gas path component.
