Abstract | An impeller manufacturing method that includes: an impeller formation step (S1) in which an impeller is integrally formed by an additive manufacturing method that uses a metal powder; an HIP processing step (S2) in which the impeller formed in the impeller formation step (S1) is processed by a hot isotropic pressurization process; and a flow path polishing step (S3) in which, after the HIP processing step (S2), fluid polishing is implemented, in which a polishing fluid containing abrasive grains is pressurized and made to flow through a flow path formed between a disc, a cover, and the blades in the impeller.
L'invention concerne un procédé de fabrication de turbine qui comprend : une étape de formation de turbine (S1) dans laquelle une turbine est formée d'un seul tenant par un procédé de fabrication additive qui utilise une poudre métallique ; une étape de traitement HIP (S2) dans laquelle la turbine formée dans l'étape de formation de turbine (S1) est traitée par un processus de mise sous pression isotrope à chaud ; et une étape de polissage de trajet d'écoulement (S3) dans laquelle, après l'étape de traitement HIP (S2), un polissage par fluide est mis en œuvre, dans lequel un fluide de polissage contenant des grains abrasifs est mis sous pression et amené à s'écouler à travers un trajet d'écoulement formé entre un disque, un couvercle et les pales dans la turbine.
このインペラの製造方法は、インペラを、金属粉末を用いた積層造形法により一体に形成するインペラ形成工程(S1)と、前記インペラ形成工程(S1)で形成された前記インペラを、熱間等方圧加圧法によって処理するHIP処理工程(S2)と、前記HIP処理工程(S2)後の前記インペラにおいて、ディスク、カバー、及びブレードの間に形成される流路に、砥粒を含んだ研磨流体を加圧しながら流通させて流動研磨を実施する流路研磨工程(S3)と、を含む。 |
