Questions about Erosion-Shielded Turbine Blade
Question 1
How does the additive manufacturing process used in this technology differ from traditional manufacturing methods for turbine blades?
The additive manufacturing process in this technology involves selectively depositing a binder solution across particulate erosion-resistant material, allowing for precise control over the material composition and distribution, which is not possible with traditional manufacturing methods.
Question 2
What are the potential environmental benefits of using erosion-shielded turbine blades in rotary machines?
The increased durability and longevity of turbine blades provided by this technology can lead to reduced maintenance requirements and longer service life, ultimately contributing to lower energy consumption and waste generation in rotary machines.
Original Abstract Submitted
A method of manufacturing an erosion-shielded turbine blade includes providing a turbine blade for use with a rotary machine. The turbine blade includes an airfoil extending between a root and a tip. The airfoil includes a pressure side and an opposite suction side, and each of the pressure and suction sides extends between a leading edge and a trailing edge. The method also includes printing a green body part by an additive manufacturing process by selectively depositing a binder solution across a particulate erosion-resistant material, and sintering the green body part to produce a post-sintering erosion shield that includes densified erosion-resistant material. The method also includes coupling the erosion shield to the leading edge of the turbine blade.
