초록 ▼

A method for manufacturing a turbine rotor assembly from dissimilar materials includes the step of preforming a turbine disc of powdered metal by direct hot isostatic pressing; machining the OD of the disc rim to an exact dimension; prefabricating a ring of airfoil elements having a circular rim with a machined ID therein fit to the OD of the turbine disc; sealing joint lines on side surfaces of the joined parts to create a vacuum at the interface with a high melt temperature sealant; thereafter diffusion bonding the joined and sealed parts by hot isostatically pressing them at temperatures in excess of 1500°F. and under fluid pressure directly applied to the parts in excess of 1000 psi to press the ring ID into intimate contact with the OD of the disc until the dissimilar materials are diffusion bonded to form a high strength butt joint therebetween.

A method for fabricating a hybrid turbine engine wheel assembly comprising: preforming a bladed metal ring from superalloy material with airfoil blades having an exact dimensional control therebetween to maintain aerodynamic flow paths through the ring and with a base rim having a premachined close tolerance ID and a front side and a rear side, preforming a disc of high strength metal having a controlled OD, press fitting the bladed ring to the disc to form a near line-to-line interface therebetween with continuously circumferentially formed front and rear joint lines and with continuous contact across the full facing surface areas of both the base rim ID and thE controlled OD of the disc from the front side to the rear side of the base rim ID thereby to prevent collapse of the interface and resultant loss of dimensional control between adjacent airfoils during a subsequent hot isostatic pressing of the joined bladed ring and disc, sealing the full extent of the joint lines with high melt temperature sealant to maintain a clean press fit at the interface between the outside diameter of the disc and the inside diameter of the bladed ring element and a sealed, pressure tight interface, and to define an exposed exterior planar extent on the bladed metal ring and the disc for receiving direct application of hot isostatic fluid without flow of such fluid into the interface, and thereafter hot isostatically pressing the joined bladed ring and disc by direct fluid pressure across the full exterior planar extent of the joined parts to form a diffused metallurgical bond between the base rim and the disc.
