Turbine nozzle and method of manufacture
Abstract
Methods of fabricating a turbomachine component and turbomachine components are provided. The method includes irradiating a layer of powder in a powder bed to form a fused region. The powder is disposed on a build plate. The method further includes a step of providing a subsequent layer of powder over the powder bed by passing a recoater arm over the powder bed from a first side of the powder bed. The method further includes repeating the irradiating and providing steps until a turbine nozzle assembly is formed on the build plate. The turbine nozzle assembly includes the turbine nozzle and a plurality of heat fins disposed within the turbine nozzle. The plurality of heat fins transfer heat away from a thermally sensitive portion of the turbine nozzle.
