Abstract:
1. A manufacturing method comprising: forming one or more grooves in a component comprising a substrate, wherein each groove extends at least partially along the substrate and has a base, a top and at least one discharge end; forming one or more craters into the substrate, such that each crater is in direct fluid connection with the respective discharge end for each groove, and wherein each crater is formed normal to an outer surface of the substrate and extending from the outer surface to a same depth as that of a respective channel; and disposing a coating over at least a portion of an outer surface of the substrate, wherein the one or more grooves and the coating together define one or more channels for cooling the component, and wherein the coating does not completely bridge each of the one or more craters, such that an exit of each crater is in fluid communication with a film exit formed through the coating, wherein each of the one or more craters has a top surface diameter at least as large as an average width of the respective channel.
