Components with laser cladding and methods of manufacture

摘要

A method of manufacture of a component is provided. The manufacturing method includes forming one or more grooves (132) in an outer surface (112) of a substrate (110). Each groove (132) has a base and an opening (136) and extends at least partially along the outer surface (112) of the substrate (110), where the substrate (110) has an inner surface that defines at least one hollow, interior space. The manufacturing method further includes using a laser cladding process to apply a laser clad material (190) over the opening (36) of the respective groove(s) (132), to at least partially define one or more channels (130) for cooling the component (100), and disposing a coating (56) over at least a portion of the outer surface (112) of the substrate (110) and over the laser clad material (190). Other manufacturing methods and a component (100) are also provided.
