Turbine blades are critical parts of turbomachinery. They primarily utilize the impact or expansion of high-temperature, high-pressure gas on the blades to drive rotor rotation and generate power output. As a result, blade performance directly influences the power and efficiency of the turbine. Typically manufactured from nickel-based alloys, turbine blades must be designed to meet demanding requirements such as high-temperature resistance, creep resistance, and fatigue resistance under extreme operating conditions. Metal 3D printing technology offers a solution that integrates lightweight design with high performance, demonstrating significant technical advantages in producing turbine blades with complex internal structures.
Challenges in Traditional Manufacturing of Complex Structures
(1) The hollow micro-holes on the upper surface of turbine blades connect to internal cooling channels. Traditional machining relies on intricate and time-consuming core-making processes, which not only extend production cycles but also struggle to ensure dimensional accuracy.
(2) Traditional machining methods are limited in optimizing the internal cooling channel designs of blades, restricting further improvements in cooling efficiency.
(3) Traditional manufacturing processes result in significant waste of metal materials, substantially increasing production costs.
