Assignee: PRATT & WHITNEY CANADA CORP.
Field: Surface technology, coating (Chemistry)
Classification: CPC F  C | IPC C  F

Claim 5:
6. A turbine blade comprising:
an airfoil made of a material having a single-crystal face centered cubic crystallographic structure;
a platform connected to the airfoil; and
a root fillet defined between the airfoil and the platform;
wherein:
a secondary crystallographic orientation of the material is based on a parameter of the root fillet;
the secondary crystallographic orientation of the material is perpendicular to a reference plane that is perpendicular to an edge of the root fillet, the edge of the root fillet being closer to the airfoil than to the platform; and
a primary crystallographic orientation of the material is at 30 degrees from a stacking line of the airfoil.
