Title: Integral channels in metal components and fabrication thereof
Usefulness: Integral channels in metal components and fabrication thereof
Summary: Used for forming an internal cooling channel in a metal body (CLAIMED), e.g. copper, aluminium, titanium, steel and magnesium of an industrial component e.g. die, combustion chamber in a space shuttle main engine and heat exchanger.
Novelty: Internal cooling channel forming method, involves rotating pin to frictionally heat metal surface, plunging pin into metal body perpendicular to metal surface and moving pin parallel to metal surface to form channel
