An article and method of forming an article are provided. The article includes a body portion separating an inner region and an outer region, an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region, and a conduit extending from an outer surface of the body portion at the aperture and being arranged and disposed to controllably direct fluid from the inner region to the outer region. The method includes providing a body portion separating an inner region and an outer region, providing an aperture in the body portion, and forming a conduit over the aperture, the conduit extending from an outer surface of the body portion and being arranged and disposed to controllably direct fluid from the inner region to the outer region. The article is arranged and disposed for insertion within a hot gas path component.

1. An article, comprising: a body portion separating an inner region and an outer region;an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region; anda conduit extending from an outer surface of the body portion at the aperture and being arranged and disposed to controllably direct cooling fluid from the inner region to the outer region,wherein the conduit includes at least one of: an orifice feature opposite the outer surface of the article selected from the group consisting of a slot, multiple holes formed in the conduit, and combinations thereof;a cross-sectional geometry of an interior surface of the conduit selected from the group consisting of non-round, star shaped, oval, square, triangular, polygonal, tear drop, varied, irregular, and combinations thereof; anda bend along the length of the conduit. 2. The article of claim 1, further comprising at least one additional aperture in the body portion, the at least one additional aperture fluidly connecting the inner region to the outer region. 3. The article of claim 2, further comprising at least one additional conduit, each of the at least one additional conduits formed over one of the at least one additional apertures. 4. The article of claim 1, wherein the conduit extends a shape of the aperture. 5. The article of claim 1, wherein the conduit includes the non-round cross-sectional geometry. 6. The article of claim 1, wherein the conduit is arranged and disposed to modify a flow of fluid from the aperture. 7. The article of claim 1, wherein the article comprises an impingement member of a turbine nozzle. 8. The article of claim 1, wherein the conduit comprises the orifice feature opposite the outer surface of the article. 9. The article of claim 8, wherein the orifice feature contracts the conduit. 10. The article of claim 8, wherein the orifice feature comprises the multiple holes formed in the conduit. 11. A component, wherein the component includes the article of claim 1, the article being arranged and disposed to direct cooling fluid toward an inner surface of the component. 12. The component of claim 11, wherein the conduit of the article directs the flow of cooling fluid from the aperture to a hot spot on the component. 13. A method of forming an article, the method comprising: providing a body portion separating an inner region and an outer region;providing an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region; andforming a conduit over the aperture, the conduit extending from an outer surface of the body portion at the aperture and being arranged and disposed to controllably direct cooling fluid from the inner region to the outer region,wherein the article includes an impingement member of a hot gas path component of a turbine engine, andwherein forming the conduit includes at least one of: forming an orifice feature opposite the outer surface of the article selected from the group consisting of a slot, multiple holes formed in the conduit, and combinations thereof;forming a cross-sectional geometry of an interior surface of the conduit selected from the group consisting of non-round, star shaped, oval, square, triangular, polygonal, tear drop, varied, irregular, and combinations thereof; andforming a bend along the length of the conduit. 14. The method of claim 13, wherein the providing of the body portion includes forming the body portion, and the providing of the aperture includes forming the aperture in the body portion. 15. The method of claim 14, wherein at least one of forming the body portion, forming the aperture, and forming the conduit comprises additive manufacturing. 16. The method of claim 15, wherein the additive manufacturing comprises direct metal laser melting. 17. The method of claim 14, further comprising forming at least one additional aperture in the body portion and at least one additional conduit on the outer surface of the body portion at the at least one additional aperture. 18. The method of claim 13, wherein the conduit is arranged and disposed to direct a cooling air flow from the aperture toward a hot spot of the hot gas path component. 19. The method of claim 13, wherein forming the conduit over the aperture comprises arranging and disposing the conduit to modify a flow of the cooling fluid from the aperture. 20. The method of claim 13, comprising forming the orifice feature on the conduit, opposite the outer surface of the body portion.
