Overcoming obstacles| A strategy to solve the difficult problem of dimensional accuracy control of turbine blades
As a key component of gas-dynamic energy conversion, the dimensional accuracy of turbine blades is not only related to whether the gas turbine can be installed smoothly, but also the key to ensure its safe operation. Turbine blade parts are complex spatial surfaces with uneven thickness, and the process of indefinite investment precision casting is complicated, in which each stage has an impact on the dimensional accuracy of the final blade, and it is difficult to take into account the geometrical characteristics of blade bending and torsion deformation and blade curvature only by relying on the method of mold surface reduction. During the process from the wax mold to the […]
Precision repair of gas turbine single crystal blades: The key to improved performance and reliability
Advances in turbine blade technology have increased the cost of new components. The cost of a single crystal blade is two to three times that of a conventional cast blade of similar size and complexity. The high cost of a single crystal component can incentivize the owner to maximize the service life of the component. As a solution to reduce the cost of replacing components, our company has created processes designed to extend the life of components. One such process is full solution regenerative heat treatment (FSR). FSR restores the microstructure and mechanical properties of the alloy to a new state. The main problem of heat treatment of single crystal […]
