<P>PROBLEM TO BE SOLVED: To provide a method for forming channels in a component with channel edges formed as sharp right angles, without further processing of substrate base metal. <P>SOLUTION: The method of fabricating the component 100 includes depositing a fugitive coating on a surface 112 of a substrate 110, where the substrate has at least one hollow interior space 114. The method further includes machining the substrate through the fugitive coating to form a groove 132 in the surface of the substrate. The groove has a base and extends along the surface of the substrate. The method further includes forming an access hole through each base of the groove to connect the respective groove in fluid communication with the respective hollow interior space. The method further includes filling the groove with a filler, removing the fugitive coating, disposing a coating 150 on the surface of the substrate, and removing the filler from the groove, such that the groove and the coating together define a number of channels 130 for cooling the component. <P>COPYRIGHT: (C)2012,JPO&INPIT |
