TURBINE BLADE CASTING

          Vacuum casting or Superalloy casting is widely used in aviation engine, aerospace engine, gas turbine, ship, metallurgy, petroleum and glass industry for its super anti-heat, anti-oxidation and anti-corrosion property. Some usage examples are

turbocharger or supercharger, turbine blade, Supercharger impeller and nozzle .

The Vacuum casting is complicated and they must be produced through the vacuum induction melting technology.

Superalloy casting mainly consists of nickel base alloy castings, chromium base alloy castings, cobalt base alloy casting and nickel-chromium base alloy castings and etc.

         Aftermarket turbine blades is that their starting point is an existing blade and nothing else. There are no CAD models, drawings, measurements, tolerances, or inspection data associated with it. However, thanks to the latest in computer tools, a blade now can be digitally recreated to exact specifications and built using the latest design and manufacturing practices. Below is an example how turbine blades are captured, reconstructed, inspected, and remade to be better than the originals
