Title:
TURBINE BLADE FOR TURBO-ENGINES AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO2006074949
Kind Code:
A8
Abstract:
A turbine blade for turbo-engines as well as a method for manufacturing such a turbine blade is disclosed. According to the task set, the turbine blades should be capable of withstanding high thermal stress and able to maintain an adequate mechanical strength even at raised operating temperatures. The turbine blades are so designed that on the surface of a core element a heat-insulating layer of a metallic open-cell foam is integrally connected to said core element by sintering. The outer contour of the turbine blade is formed with at least one shell element. The shell element comprises a nickel-base alloy, which is also integrally connected by sintering to the open-cell foam which forms the heat-insulating layer.
