| 摘要 |
A method for providing a fluid cooling system within a high temperature component is described. At least one microchannel is formed in an external surface of the component; and one or more coolant passage holes are then formed, extending from at least one of the microchannels to an interior region of the component. A layer of a metallic structural coating is then applied over the external surface. At least one slot, or a set of relatively small passive cooling holes, are then formed through the metallic structural coating; extending into at least a portion of the microchannels. A second coating layer is then applied over the first layer. In some embodiments, a sacrificial material is deposited into the microchannels before the first coating layer is applied. Related articles are also described.
