Manufacturing procedure for article such as turbine blade from laserprojected metal powder uses stacked peripheral and internal layers

The procedure consists of forming by laser projection of metal powder a stack (10) of peripheral layers (8) and another stack (20) of interior layers (18). An article made from the stacked layers is produced so that one section of the article contains peripheral layers and another part contains inte...

Zusammenfassung:The procedure consists of forming by laser projection of metal powder a stack (10) of peripheral layers (8) and another stack (20) of interior layers (18). An article made from the stacked layers is produced so that one section of the article contains peripheral layers and another part contains interior layers, each layer being made from two metal powders having different grain sizes. The article can be produced, for example, on a substrate formed by the foot of a turbine blade or disc. L'invention se rapporte à un procédé de fabrication d'un objet (1) par projection laser de poudre métallique, comprenant la réalisation, selon une direction d'empilement (12), d'un empilement (10) de couches périphériques (8) obtenues par projection laser de poudre métallique, ainsi que la réalisation, selon ladite direction d'empilement, d'un empilement (20) de couches intérieures (18) également obtenues par projection laser de poudre métallique, de sorte que l'empilement de couches périphériques se trouve situé autour de l'empilement de couches intérieures.
