Abstract:
A turbopump such as a liquid oxygen (LOX) turbopump for a liquid rocket engine is formed using a metal additive manufacturing process in which a single-piece impeller is formed within a single piece housing, the impeller being trapped within the single piece housing. The impeller is formed with an axial bore in which a shaft is inserted after the impeller and housing have been formed. The turbopump includes a protective coating that forms a reaction resistant surface on the base metal in areas of the base metal that are exposed to an oxidizer during pumping. The protective coating may be an enamel glass, a superalloy layer beneath an enamel glass layer, a composite layer of a mixture of enamel glass and superalloy, a composite mixture of oxide and superalloy, or a composite layer of a mixture of enamel glass, superalloy, and oxide.

Claim (Index 2):
The liquid rocket engine oxidizer turbopump of  claim 1 , wherein an entirety of surfaces ( 35 ) of the oxidizer turbopump that are exposed to an oxidizer during pumping have a protective coating ( 36 ) of at least one protective material to prevent reaction of the oxidizer with the surfaces ( 35 ).
