    Abstract: A blade for a turbomachine includes an airfoil extending radially between a root and a tip with a tip shroud coupled to the tip of the airfoil. The tip shroud includes a platform having an outer surface extending generally perpendicular to the airfoil. The tip shroud also includes a forward rail extending radially outward from the outer surface of the platform. The forward rail is oriented generally perpendicular to a hot gas path of the turbomachine. A cooling cavity is defined in a central portion of the platform. The tip shroud also includes a cooling channel extending between the cooling cavity and an ejection slot formed in the forward rail. The ejection slot is positioned radially outward of the outer surface of the platform of the tip shroud.

    Abstract: A gas manifold for single-nozzle deposition chambers comprising a base having a top surface and bottom surface defining a thickness; a primary nozzle having an inlet and outlet extending through the thickness of the base; and a secondary nozzle having an inlet extending partially through the top surface of the base and at least one channel extending a distance from a sidewall of the base having an outlet, the channel in fluid communication with the inlet of the secondary nozzle. The inlet of the primary nozzle has a hollow protrusion extending from the top surface of the base into the gas feed. The channel of the secondary nozzle includes a bend between the sidewall of the base and the outlet configured to pass between a first direct energy source and second direct energy source, the first energy source and second energy source disposed on a top wall of a chamber.
