Interaction effects of alkaline and acid electrolytes with intermetallic γ’-phase on surface of nickel superalloys

The effects of interaction between the intermetallic γ’ phase and matrix γ phase based on a nickel solid solution with acidic and alkaline electrolytes at room and high temperatures are studied by high-resolution metallographic techniques using scanning electron microscopy, local energy-dispersive X...

Description
Summary:The effects of interaction between the intermetallic γ’ phase and matrix γ phase based on a nickel solid solution with acidic and alkaline electrolytes at room and high temperatures are studied by high-resolution metallographic techniques using scanning electron microscopy, local energy-dispersive X-ray spectroscopy, and wavelength dispersive X-ray fluorescence spectroscopy. Defects formed on the surface of casts of turbine blades are considered, and recommendations to redress them are provided.
