System for protecting turbine engine surface from corrosion

According to various embodiments, a system includes a turbine engine component (212) that includes a first material having a surface (215) exposed to a fluid flow path and a sacrificial anode layer (252,254) disposed on the surface (215). The sacrificial anode layer (252,254) includes a second mater...

More Information
Summary:According to various embodiments, a system includes a turbine engine component (212) that includes a first material having a surface (215) exposed to a fluid flow path and a sacrificial anode layer (252,254) disposed on the surface (215). The sacrificial anode layer (252,254) includes a second material that is electrochemically more active than the first material and the second material is configured to preferentially corrode to protect the first material from corrosion.
