METHOD FOR MANUFACTURING A METALLIC COMPONENT

摘要

A method for manufacturing a metallic component is disclosed. The method includes forming a metallic component with a support structure using an additive manufacturing process. The support structure includes support walls arranged to form flow passages with a predetermined cross-sectional area. The method also includes placing the metallic component with the support structure into a chamber and sealing the chamber. The method further includes introducing a fuel mixture into the chamber after sealing the chamber. The method still further includes igniting the fuel mixture in the chamber to remove one or more of the support walls of the support structure from the metallic component.

1. A method for manufacturing a metallic component, the method comprising:
forming the metallic component with a support structure using an additive manufacturing process, the support structure including support walls arranged to form flow passages with each passage including a cross-sectional area that is large enough to allow a fuel mixture to flow there through and a flame to propagate there through without choking the flow of the fuel mixture and without choking the flame propagation; placing the metallic component with the support structure into a chamber and sealing the chamber; introducing the fuel mixture into the chamber after sealing the chamber; and igniting the fuel mixture in the chamber to remove one or more of the support walls of the support structure from the metallic component.
