Superalloy turbine wheel used for Locomotive and Marine turbocharger, turbo turbine wheel be finished by integral casting. And casting method of turbine wheel is lost wax investment & vacuum casting, casting surface smoothness can meet Ra3.2μm, production process of turbine wheel is
Silica sol process. The blade thickness is 0.5mm. For turbine wheel, we can do thw kinds of type: radial turbine wheel and axial turbine wheel.
The material of turbine wheel is superalloy IN713c, Please see the material chemical composition:
