METHOD FOR PRODUCING A METAL PART FOR AN AIRCRAFT TURBO-ENGINE |
摘要 |
A method for producing a metal part, the part including, in particular, a first set of elements having a small thickness, and a second set of elements having a large thickness, the method including: forming a peripheral portion of the elements of the second set of elements by selectively melting a powder by scanning the surface of the powder layer with a laser beam or with an electron beam; using the peripheral portion of the elements of the second set of elements as a mould by carrying out an operation of filling an inner area defined by the peripheral portion with liquid metal; cooling the metal part to solidify the inner area defined by the peripheral portion and filled with metal. |
