Abstract
An apparatus and method for protecting an inner radial surface of a radial member of a turbomachine from corrosion are provided. The method may include shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner. The method may also include heating the radial member to increase a diameter of the inner radial surface of the radial member, and inserting at least a portion of the corrosion-resistant liner into the radial member. The method may further include attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.
Claims9
A method for protecting an inner radial surface of a radial member of a turbomachine from corrosion, comprising:
- shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner;
- heating the radial member to increase a diameter of the inner radial surface of the radial member;
- the diameter of the inner radial surface of the radial member being less than a diameter of the outer radial surface of the corrosion-resistant liner prior to heating;
- inserting at least a portion of the corrosion-resistant liner into the radial member;
- and
- attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.
